Calculate 5/9 × 6/25

Step by step

The question

Question: work out 5/9 × 6/25.

1 Cancel first

Before we multiply, we make the numbers smaller.

5 on top and 25 at the bottom both divide by 5.

6 on top and 9 at the bottom both divide by 3.

A top and a bottom divided by the same number: the answer stays the same.

So we multiply smaller numbers.

2 Multiply tops and bottoms

To multiply fractions, we do top times top, and bottom times bottom.

1 times 2 is 2.

3 times 5 is 15.

Can we make it simpler?

No number goes into both 2 and 15, except 1.

So it stays like this.

So the answer is 2/15.

Let's look back.

First: cancel first.

Last: multiply tops and bottoms.
