Step by step
The question
Question: which property is this: (5 × 2) × 3 = 5(2 × 3)?
(5 × 2) × 3 = 5(2 × 3)
1 Compare the two sides
Look at both sides.
The brackets moved.
the brackets moved
So it is the associative property of multiplication.
= associative property of multiplication
2 Check
Let's check: work out both sides.
The left side is 30.
The right side is 30.
Both the same.
So the answer is right!
(5 × 2) × 3 = 30, 5(2 × 3) = 30
Let's look back.
First: compare the two sides.
Last: check.
Answer
= associative property of multiplication
