Introduction to 4th grade math solving:
Mathematics is the vast area, which involves both simple problems and complex problems. Solving 4th grade math problems is very easy, because 4th grade math problems involves simple basic concepts. Once we understand the basic concepts, solving 4th grade math problems looks very easy.
In this article of 4th grade math solving, example problems and practice problems related to 4th grade math are given.
Understanding The Perimeter of a Square is always challenging for me but thanks to all math help websites to help me out.
Solving example problems for 4th grade math:
Example 1:
Calculate the perimeter of Cube having the side length of 10 cm.
Solution:
Perimeter = 12 a
= 12 * 10
= 120 cm
Example 2:
Thrice a given number is 45. Find the number.
Solution: Let the unknown number be x
3 x = 45
x = `<< 45/3>>`
= 15
Example 3:
Out of 420 seats in a theatre,360 seats are occupied. Find the percentage of seats occupied.
Solution:
Total seats = 420
Occupied seats = 360
Percentage = `<< 360 / 420>>` x 100
= `<< 36/42>>` x 100
= 85.7
Example 4:
Robert bought a doll for `$` 27 and he sold it for `$` 36. What is his gain?
Solution:
Cost price of doll = $ 27
Selling price of doll = $ 36
Profit or Gain = Selling price - Cost Price
= 36 - 27
= $ 9
Example 5:
Julie buys an ornament that costs `$` 270. If the sales tax rate is 4%. What is the total amount she must pay for the ornament?
Solution:
Sales tax = 4% of the price tax
= 4% x 270
= 0.04 x 270
= 10.8
Final price = price before the tax + sales tax
= 270 + 10.8
= $ 280.8
Example 6:
Evaluate: a3. b2 when a = 2 and b = 2
Solution:
a3x b2 = 23 x 22
= 8 x 4
= 32

Practice problems for 4th grade math:
1) Calculate the perimeter of Cube having the side length of 5 cm.
2) Thrice a given number is 60. Find the number.
3) Out of 380 seats in a theatre,270 seats are occupied. Find the percentage of seats occupied.
4) Hamilton bought a doll for `$` 17 and he sold it for `$` 23. What is his gain?
5) Jenifer buys an ornament that costs `$` 370. If the sales tax rate is 3%. What is the total amount she must pay for the ornament?
6) Evaluate: a^2. b^3 when a = 4 and b = 3
Answer key:
1) 60 cm 2) 20 3) 71.05 4) `$` 6 5) `$` 381.1 6) 432
