1 answer:
<u>Answers</u>
2.47 + 7.1 = 9.57
7.1 + 2.47 = 9.57
9.57 - 2.47 = 7.1
9.57 - 7.1 = 2.47
<u>Explanation</u>
A fact family is a group of math facts using the same numbers. In the case of addition/subtraction, you use three numbers and get four facts.
In this case we are going to write two different addition facts and two different subtraction facts as follows:
2.47,9.57,and 7.1
<em><u>Addition facts</u></em>
2.47 + 7.1 = 9.57
7.1 + 2.47 = 9.57
<em><u>Subtraction</u></em>
9.57 - 2.47 = 7.1
9.57 - 7.1 = 2.47
