Answer:

7 3/4

Step-by-step explanation:

We start by multiplying by 2 so that we can have the same denominator

so...

1  x 2   = 2

_____

2 x 2    = 4

2/4 + 1/4 = 3/4

For the whole numbers, just add them together

that means....

5 + 2 = 7

All together,

Our final answer is 7 3/4

Hope this helps!!♥︎
