I Need Help on 4th Math

Introduction to I need help on 4th math:

The topics involved in four grade math help are  patterns, addition, measurement, subtraction, number sense, multiplication, functions, fractions & mixed numbers, division, algebra, decimals, adding and subtraction of decimals and probability & statistics. In this article "I need help on 4th math" we shall deal with expanded form, median & mode, and measurements. The following are the examples related to I need help on 4th math grade.

I like to share this Subtracting Mixed Fractions with you all through my article.

I Need Help On 4th Math Problems:


Example 1: Find the value form the expanded form 9 × 10000 + 3× 1000 + 9 × 10 + 20

Solution:  9 × 10000 + 4 × 1000 + 9 × 10 + 20

= 90000 + 4000 + 90 + 20

=> 94110.

Example 2: Find the mode for given set of data. 63, 31, 28, 29, 31, 62, 88

Solution: Mode:The mode is the number that occurs most often in a set of data.

Form the given data set we can say that 31 is the number that has occurred twice.

For the given set of data Median = 31.

Example 3: Find perimeter of a square with length 12.

Solution: The perimeter of a square = 4 * a ( a-> length)

Here length =12, So perimeter of square = 4 * 12 = 48

Example 4: Find the circumference of a circle with diameter 24.

Solution:  The circumference of a circle = 3.14(pi) * diameter of the circle.

Here diameter = 10, So Circumference of a circle = 3.14 * 24

Therefore the Circumference of a circle =   75.36

Example 5: Find the median of 8, 2, 7, 5, 3, 9

Solution:Evaluate the total numbers from the given set of values.

From the given set of values, there are totally 6 numbers, Which is even,

Now arrange the total numbers in ascending order,

2, 3, 5, 7, 8, 9

As the given set of numbers is even , Sort out two middle numbers from the above given list of numbers,

Which is  5 & 7 are the two middle numbers,

In order to find the median, add both middle terms and divide by 2,

Adding both numbers `(5+7)/(2)` = 6,  So,median=6.
