Question

Juanita wrote 3 X 47 as 3 X 40 + 3 X 7. What property did she use to rewrite the expression?

Answer 1

Answer: Distributive property

Explanation:

Since
`47=40+7`

Thus, the product
`3*47` is equivalent to

`3*(40+7)`

The distributive property says that multiply a sum by multiplying each addend separately and then add the products.

Thus, by this property above product can be written as:

`3*40+3*7\\`

Hence, Juanita used distributive property to rewrite the expression.
