Answer

2 19/20

Work Step by Step

1. 3/4 and 4/5 need to have common denominators, so make the denominator 20. 2. Now you should have 7 15/20 and 4 16/20. Now you see that you would get a negative when you subtract the fractions, so you need to rewrite 7 15/20 as 6 35/20 so you can subtract. 2. Subtract: 6 35/20 - 4 16/20. 3. Answer: 2 19/20
