## The Lesson

A fraction of a number lets us find part of a number. Imagine 3/5 (three-fifths) of a class of 25 students love mathematics. 15 students (3/5 of 25) love mathematics.

## How to Find the Fraction of a Number

To find the fraction of a number you have to multiply the fraction by the number:

Hint: 'of' means '×' when finding a fraction of a number.

## Question

What is 35 of 25?

# 1

Write a fraction of a number as a fraction × a number, like the formula above. In our example, the fraction is 35 and the number is 25.

# 2

Divide the top number (called the numerator) of the fraction (3) by the bottom number (called the denominator) of the fraction (5).

3 ÷ 5 = 0.6

# 3

Multiply the answer (0.6) by the number (25).

0.6 × 25 = 15

We have found 35 of 25.
