Aimee must add together the following numbers:3.50 + 4.00 + (−1.25) + (−7.50) + 5.25 + 2.00As her first step, Aimee writes:(3.50
+ (–7.50)) + (–1.25 + 5.25) + (4.00 + 2.00)Which is the best explanation of what Aimee did in this step? A.Aimee used the Associative and Commutative Properties to put opposite numbers together.
B.Aimee used the Identity Property to put numbers with the same values after the decimal point together.
C.Aimee used the Associative and Commutative Properties to put numbers that are easy to add next to each other.
D.Aimee used the Inverse Property to pair each positive decimal with a negative decimal so that they will cancel out.
<h2>C. Aimee used the Associative and Commutative Properties to put numbers that are easy to add next to each other.</h2>
Step-by-step explanation:
The given problem is
Aimee's first step is
As you can observe Aimee associated all numbers in a way that helped her to percieve clearl the operations she needs to do. That's a proper use of the associative property.
Therefore, the right answer is C., because Aimme used the associative and commutative properties to make it easier for her.
There are 1000 mililiters in one liter. Since there are two liters, it means there´s 2000 mililiters. He drink half of it, so 1000 mililiters are left.
