Fractions of a number
key notes :
1. Understanding Fractions of a Number:
- A fraction represents a part of a whole. It consists of a numerator (top number) and a denominator (bottom number).
- When finding a fraction of a number, you are determining how much of that number is represented by the fraction.
2. Steps to Find a Fraction of a Number:
- Step 1: Divide the number by the denominator of the fraction.
- Example: To find 1/4 of 20, divide 20 by 4 → 20 ÷ 4 = 5.
- Step 2: Multiply the result by the numerator of the fraction.
- Example: 1/4 of 20 → 5 × 1 = 5.
- Therefore, 1/4 of 20 is 5.
3. Examples:
- 1/2 of 16: 16 ÷ 2 = 8, and 8 × 1 = 8. So, 1/2 of 16 is 8.
- 2/3 of 18: 18 ÷ 3 = 6, and 6 × 2 = 12. So, 2/3 of 18 is 12.
Learn with an example
😐 What number is 1/2 of 16?
Divide 16 into 2 equal groups. Find how many are in each group.
16 ÷ 2 = 8
There are 8 in each group.
8 is 1/2 of 16.
😐 What number is 1/3 of 15?
Divide 15 into 3 equal groups. Find how many are in each group.
15 ÷ 3 = 5
There are 5 in each group.
5 is 1/3 of 15
😐What number is 1/7 of 14?
Divide 14 into 7 equal groups. Find how many are in each group.
14 ÷ 7 = 2
There are 2 in each group.
2 is 1/7 of 14.
