Answer is 1 13/16
Step by step
Difference means to subtract
9 5/8 minus 7 13/16
Change the first fraction so the denominator is the same as the second (16)
5/8 = 10/16
Now we have
9 10/16 - 7 13/16
Since we can’t subtract 13 from 10, we have to borrow a whole number from 9, and call it 16/16. Add 16/16 to 10/16 now we have 26/16.
8 26/16 - 7 13/16
Subtract
= 1 13/16
