Question

1. what related facts can you make using the following numbers: 2, 5, 7? * 1 point

2 + 7 = 9
7 + 2 = 9
9 - 2 = 7
9 - 7 = 2
11 + 2 = 9
2 + 11 = 9
11 - 2 = 9
11 - 9 = 2
7 + 5 = 12
5 + 7 = 12
12 - 7 = 5
12 - 5 = 7
5 + 2 = 7
2 + 5 = 7
7 - 2 = 5
7 - 5 = 2
a
b
c
d

Explanation:

Step1: Check numbers in options

We need to use 2, 5, 7 to form related addition and subtraction facts. Option A uses 2 and 7 to get 9 which is not relevant. Option B uses 11 which is not among 2, 5, 7. Option C uses 5 and 7 to get 12 which is not relevant.

Step2: Analyze Option D

Option D has addition facts 5 + 2 = 7 and 2+5 = 7 and subtraction facts 7 - 2 = 5 and 7 - 5 = 2 using only 2, 5, 7.

Answer:

D. 5 + 2 = 7, 2 + 5 = 7, 7 - 2 = 5, 7 - 5 = 2
