It is asking you to simplify the fraction 
by finding an equivalent fraction with a smaller number as the denominator.
Let's practise
Simplify
- Read the question and then read it again. What is it asking you to do?
Show me
- To simplify a fraction, the numerator and denominator are divided by the same number.
We need to find a multiplication table that includes both numbers in the fraction.
Show me
So, we are looking for a multiplication table where both 15 and 24 appear.
15 and 24 both appear in the three times table.
- To keep the numerator and denominator in proportion, we divide both the numerator and the denominator by 3.
Show me
15 ÷ 3 = 5
24 ÷ 3 = 8
- What is your answer?
Show me
= 
- Check your working using the inverse.
Show me
5 × 3 = 15
8 × 3 = 24
So, is equivalent to
