Introduction to 7th grade math need help
7th grade math need help is about the problems and chapters of math that are studied and revised in the grade 7. 7th grade math need help involves chapters like addition, subtraction, multiplication and division, fractions, decimals, measurements, area, volume, surface area, statistics, word problems, scientific notation etc.These topics will be simpler and easier one to learn and to perform calculation with the problems . 7th grade math need help will be more interesting one to work out the problems.
Examples on 7th grade math need help
Add the six digit number 8 4 57 1 2 + 1 2 4 2 5 1
Solution
8 4 5 7 1 2
1 2 4 2 5 1 +
----------------
9 6 9 9 6 3
----------------
2. Subtract `3/7` - `1/3`
Solution
Here the denominators are different
So we have to find the LCM
The LCM of 7, 3 = 21
` (3xx3)/ (3xx7)` = `9/21`
`(1xx7) / (3xx7)` = `7/21`
Now we subtract
`9/21- 7/21`
`(9-7)/21`
`2/ 21` is the solution.
3. Find the area and perimeter of the rectangle if length is 9 cm and width is 6 cm.
Solution
Length of the rectangle = 9 cm
Width of the rectangle = 6 cm
Formula to calculate the area of the rectangle = length * width
So
Area of the rectangle given = 9 * 6
= 54 square centimeter
Perimeter of the rectangle = 2(length + width)
= 2 (9 + 6)
= 2(15)
= 30 cm

4. Find the area and perimeter of a square of the side a = 10cm
Solution
The side of the square = 10 cm
Formula to calculate the area of the square = `a^2` or (side * side)
Area of the square = 10 * 10
= 100 square centimeter.
Formula to calculate the perimeter of the square is 4* side
Perimeter of the given square = 4 * 10
= 40 cm
5. Find the number suffixes of the series given 35, 40, 45, 50, 55
Solution
The given series is 35, 40, 45, 50, 55
In this series the number is increased with 5
So the number suffixes of this series is 60, 65 and goes on
