Step by step

The question

Question: which property is this: 2/3 × 3/2 = 1?

23 × 32 = 1

1 Compare the two sides

Look at both sides.

A number times its flip is 1.

a number times its flip is 1

So it is the inverse property of multiplication.

= inverse property of multiplication

2 Check

Let's check: work out both sides.

The left side is 1.

The right side is 1.

Both the same.

So the answer is right!

2 over 3 × 3 over 2 = 1, 1 = 1

Let's look back.

First: compare the two sides.

Last: check.

Answer
= inverse property of multiplication

Your turn

Try this one yourself, then check:

82 × 28 = 1
