Answer:
A preposition
Explanation:
Sum = adding correct.
That means we need to add 7+5 =12
and add the /8 to it
12/8
But thats improper so we need to simplify.
1 4/8
But theres still some simplifying.
4/8=1/2
That means your answer is 1 1/2
Hope this helped :)
I think you add two more every row so there would be 13 in the 7th row
