The answer to this question would be C, 9. The reason for is cause you remove the parentheses then add the numbers 1.2 + 7.8=9.
Answer: The answer is A 1/16
The number 7 cannot be used to write related number sentences because it wouldn't fit into the equation & make it true.
9 + 5 = 14

14 - 5 = 9
14 - 9 =5
Nowhere in any of these equations can the #7 go in, & make these number sentences true.
