You can do this subtraction by setting it up as a regular subtraction and borrowing.

Since you can't subtract 3/5 from nothing, you need to borrow 1 from 12. 1 can be written as 1/1, 2/2, 3/3, 4/4, 5/5, 6/6, etc. Since the fraction we already have is 3/5, we will borrow 1 from 12 and will write it as 5/5.

@Kaelyn78 You are correct. The way the problem was written above, it means 12 - 4 + 3/5, but the poster meant to write 12 - 4 3/5, where 4 3/5 is a mixed numeral. That's why the poster used the word "and" not "plus".
