Question

Use the commutative property to find the equal expression for each addition or multiplication expression

5 x 7

10 + 24

3 x 1

7 x 5

Answer 1

Shown below.

Explanation:

What is commutative property?

The commutative property is a property of binary operations that states that the order of the operands does not affect the result of the operation. In other words, if you swap the order of the operands, you will still get the same result. This property holds true for addition and multiplication but not for subtraction and division.

1. So, 5 × 7 can be swapped to make it 7 × 5.
2. 10 + 24 can be swapped to make it 24 + 10.
3. 3 × 1 can be swapped to make it 1 × 3.
4. 7 × 5 can be swapped to make it 5 × 7, which is the same as the first expression.

Therefore, the equivalent expressions in order are 7 × 5, 24 + 10, 1 × 3 and 5 × 7.
