Keep the denominators the same and subtract the numerators. So for example in your example:
7/8 - 3/8
Leave the 8 alone. Subtract 3 from 7.
7 - 3 = 4
So answer is:
4/8
Sometimes they may have to simplify the answer, and in this case, 4/8 could be simplified to 1/2
$132.55-($15*12)=$132.55-$180=$-47.45
So then he would have owed 47.45 dollars!
Answer:
the answer would be 3.4 + 4 = 7.4 .
