How do I use the decimals 2.47, 9.57, and 7.1 to write two different addition facts and two different subtraction facts?

Answers
2.47 + 7.1 = 9.57
7.1 + 2.47 = 9.57
9.57 - 2.47 = 7.1
9.57 - 7.1 = 2.47
Explanation
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
Addition facts
2.47 + 7.1 = 9.57
7.1 + 2.47 = 9.57
Subtraction
9.57 - 2.47 = 7.1
9.57 - 7.1 = 2.47

Using the decimals 2.47, 9.57, and 7.1, we can create two addition facts: 2.47 + 7.1 = 9.57 and 7.1 + 2.47 = 9.57. The two subtraction facts are 9.57 - 2.47 = 7.1 and 9.57 - 7.1 = 2.47. These facts illustrate how addition and subtraction relate these three numbers to one another.
