Question

Carmen is simplifying the expression (6.21 + 0.93) + 0.07 She recognizes that 0.93 and 0.07 will combine to equal 1, so she would like to find that sum before she adds 6.21. Which property will allow Carmen to do this without changing the value of the expression?

Answer 1

6.21 + (0.93 + 0.07)

Associative property.

Explanation:

took the test in edge <3

Answer 2

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.
