Conner Robles · Answer 1

For this case we have the following expression:

(6.21 + 0.93) + 0.07

We apply the associative property of the addition to rewrite the expression.

This property indicates that, when there are three or more terms in these operations, the result does not depend on the way in which the terms are grouped.

We have then:

6.21 + (0.93 + 0.07)

Answer:

6.21 + (0.93 + 0.07)

Associative property.
