Question

Angela ordered 2 glass paperweights. The volume of each paperweight is 5 cubic inches, and the density of the glass is 1.5 ounces per cubic inch. Angela can use the calculation below to find the total weight of her order.

2×(5×1.5)

How can Angela simplify the calculation using only the associative property of multiplication?

Drag and drop the appropriate number or expression into each box.

Answer 1

first box is (2 times 5) next box is 1.5

Explanation:

i took K12 test :)

Answer 2

`(2* 5)* 1.5`

Explanation:

Since, according to associative property of multiplication,

a(bc) = (ab)c,

Where a, b and c are any real numbers,

Here, the given expression,

2 × ( 5 × 1.5 ),

By applying the associative property of multiplication,

( 2 × 5 ) × 1.5,

Hence, the appropriate expression in the first box is '(2×5)'

And, the appropriate number in the second box is '1.5'.
