Example problems for solving mathematics practice:


Example problem 1: Write the expression for the following:” g is added by 12 and decreased by 5”

Solution:

Given g is added by 12 and decreased by 5

g + 12 -5 = g + 7

Answer: g + 7

Example problem 2: Mrs. Michael baked apple pies for her family. The boys ate `3/5 ` of a pie and the girls ate `1/4` of a pie. How much more pie did the boys eat than the girls?

Solution:

We have to find how much more pie the boys ate by subtracting `1/4` from `3/5` .

You can use 5 as the common denominator.

Multiply the numerator and denominator of `1/4` by 5:

`1/4 * 5/5 = 5/20`

Multiply the numerator and denominator of `3/4 ` by 4:

` 3/4 * 4/4 = 12/20`

Now subtract: `12/20 - 5/20 = 7/20`

Answer: The boys ate `7/20` of a pie more than the girls ate.

Range Mean in Mathematics

Introduction on what does range mean in mathematics:

The length of the interval which is small by containing all data is defined as the range. In mathematics it is used in the identification for the dispersion in statistics. The measurement of the range is based on the poor as well as weak measure of the data. The range is measured by using the same units. For example, if range is used in measuring population it uses some of the mean distribution. I like to share this Inter Quartile Range with you all through my article.


What does range mean in mathematics:-Range definition


Definition of range which is used in mathematics:

Range is the simplest measure of dispersion.

It is defined as the difference between the biggest and the smallest values in the series. The equation for range defining what it means in mathematics is given as,

Range = Vmax - Vmin

where Vmax is the maximum value,

Vmin is the minimum value.

Coefficient of range:

In mathematics the coefficient of range is calculated by using the formula which means the range is given as,

Coefficient of range = `(Vmax - Vmin)/(Vmax + Vmin)`

Median in mathematics:

The median is used in the mathematics which means what is the middle term from the given data. The middle term in mathematics is found by arranging the data in ascending and descending order.

If the number of data is in odd number then the middle term is considered as the median which means the middle term. If the number of data is in even number then the middle two terms are added and divided by two for getting the median.

Mode in mathematics:

The mode is the term which means identifying the frequently occurred terms.

Understanding What is a Mean is always challenging for me but thanks to all math help websites to help me out.

Example problems to learn what does the range mean in mathematics


1. The datas are 15, 30, 40, 45, 56, 64. What is the range for the given data?

The maximum value = 64

Minimum value = 15

Range = Vmax - Vmin

= 64 - 15

= 49

Coefficient of range = `(Vmax - Vmin)/(Vmax + Vmin)`

= `(64 - 15)/(64 + 15)`

=   `(49)/(79)`

= 0.625

2. The largest value of the data is 72. If the range of data is 25, what is the smallest value of the data?

Maximum value = 72

Range = 25

Minimum value = ?

Range = Vmax - Vmin

25 = 72 - Vmin

Vmin = 72 - 25

= 47

Hence 47 is the minimum value.

3. What is the mode of the following numbers 11, 12, 6, 5, 6, 8, 6?

Here the mode is 6 because it occurs three times in the given numbers.

4. What is the mode of the given data 7, 11, 4, 11, 13, 14, 4, 4, 11?

Here the mode is 11 and 4 since both the numbers occur three times.

5. Find the median for the following numbers 2, 4, 6, 8, 7, 10, 9?

Step 1: Arrange the numbers in ascending order.

2, 4, 6, 7, 8, 9, 10.

Step 2: Since the given numbers are odd then the middle term is 7.

6. What is the median for the following numbers 3, 6, 7, 4, 2, 11.

Step 1: Arrange the numbers in ascending order.

2, 3, 4, 6, 7, 11.

Step 2: Since the given numbers are even then add teh two middle terms.

Median = `(4+6)/(2)`

= `(10)/(2)`

= 5.

Hence the median is 5.

Learn online basic mathematics study example problem


Example:

Find 10xy – 18xy

Solution:

Here the subtraction is possible because the given terms are like terms, but here we have to subtract the grater number from a small number.

10y – 18xy = (10 – 18)xy

= – 8xy

Example:

Solve for x:

8 x - 2 = 4 x + 14

Solution:

8 x - 2 = 4 x + 14

Subtract 4x from both sides of the equation

8x – 4x – 2 = 4x – 4x + 14

4x – 2 = 14

Add 2 to both sides of the equation

4x – 2 + 2 = 14 + 2

4x = 16

Divided by 4 both side of the equation

x = 4

Example:

Find the ratio of 40 cm to 8meter.

Solution:

8meter = 8 × 100cm = 800 cm

Therefore required ratio = 40: 800

= 4: 80

= 1: 20

Example:

A room in rectangle form the length of the room is 20cm and the breadth of the room is 15cm. Find the room area and perimeter.

Solution:

Room length is l= 20cm
Room breadth, b= 15cm
Area of rectangle formula A = l x b sq units

= 20 x 15

= 300

Therefore the room area is A = 300 sq.cm

Perimeter of rectangle room, P        = 2l + 2b units

= 2 x 20 + 2 x 15

= 40 + 30

= 70

Therefore perimeter of the room is, P = 70 cm

Where all recreational mathematics is used;


The recreational games are not necessarily involves any mathematical process of adding or subtracting any numbers, it’s just a fun game to make them understand the fundamentals and basics. All this games carries some rules and regulations to follow but not much of calculations involved. There is a chance of interaction between the players which widens the horizon of learning some techniques without any risk. The recreational mathematic is advised at the early stage of the schooling amongst the growing children.

Lots of short stories which mentions about this recreational mathematics are seen in libraries which can be recommended. Normal way playing can have this type of mathematical problems under which any child can grasp the basics of this subject. Recreational mathematics should also be played during leisurely time of family members or during holidays with friends and relatives. At the end we conclude with the opinion of having compulsory mathematical games in daily routine will help in improving the skill of a child.

Introduction to learn mathematics solutions:

In mathematics solutions, we can learn many topics like algebra, differential calculus, trigonometry, geometry, etc. Here we can see mathematics functions and mathematics equation in algebra.Mathematics functions are help to learn one or more degree polynomial function with one or more variables. The example to learn mathematics function is, f(x) = 5x + 11, `f(x) = x^2 + 8x - 5`

Mathematics equations are help to learn one or two variables with one or more order values. The example to learn mathematics equation is y = 15x + 5. `y = 5x^2 + 8x - 2`


Examples to learn mathematics equation solutions:


Learn solutions for mathematics equations example problem 1:

Learn the factors for the given mathematics equations,` x^2 - 5x + 4 = y`

Solutions:

Plug y = 0, to find the factor for the given mathematics equation.

We can separate the equation as sum and product of roots,

This is in the form of

`x^2` + (Sum of the roots) x + (Product of the roots) = 0

By comparing the given equation we can get,

Sum of the roots = -5

Product of the roots = 4

The possible number of outcome for product of the roots is `(-4)xx (-1) and (4)xx(1)`

By comparing the product of root value, we can obtain the sum of the roots,

To obtain the value for sum of the roots -5, consider (-4) + (-1)

Now substitute this sum of roots values in the equation, we get

`x^2 - 4x - x + 4 = 0`

Now, bring out x as common in the first two terms and -1 as common in the next two terms

x(x - 4) - 1 (x - 4) = 0

(x - 4) (x- 1) = 0

Thus, the factors for the given mathematics equation is (x - 4) (x - 1)

Learn solutions for mathematics equations example problem 2:

Learn the given mathematics equation by reducing the given expression, 3(5y + 8) = 8 – 5x.

Solutions:

Step 1: Given expression,

3(5y + 8) = 8 - 5x

Step 2: By the use of distribute property

15y + 24 = 8 - 5x

Step 3: Add -24 on either side,

15y + 24 – 24 = 8 - 5x - 24

15y = -16 – 5x

Step 4: Divide by 15 on either side

` (15y) / (15) = (-16)/ (15) - (5x)/ (15)`

Step 5: By simplifying, the expression we get,

` y = (-16)/ (15) - (x)/ (3).`
