Final answer:
The expression that would be easier to simplify using the commutative property is C. 1/4 + 1/2 + 3/4.
Step-by-step explanation:
In order to determine which expression would be easier to simplify using the commutative property, we need to consider the order of the numbers in each expression. The commutative property states that the order of addition or multiplication does not change the result. Therefore, we want to choose the expression that would result in a simpler calculation after changing the order of the numbers.
A. 130 + 70 + (-61): The commutative property does not apply here because we are only adding numbers. The order does not affect the calculation.
B. -30 + (-90) + 12: The commutative property does not apply here either because we are only adding numbers.
C. 1/4 + 1/2 + 3/4: The commutative property does apply here because we are adding fractions. We can change the order of the fractions without changing the result. This expression would be easier to simplify using the commutative property.
D. 3/2 + 1/2 + (-57): The commutative property does not apply here because we are adding fractions and a whole number.
Therefore, the expression that would be easier to simplify using the commutative property is C. 1/4 + 1/2 + 3/4.
