Answer:
1 and 7/10
Step-by-step explanation:
Start off with making the fractions have common denomators by making 1/2 into 5/10 and 4/5 into 8/10
3-1=2, but the fractions go into negative, eating into the 2 whole number.
5/10-8/10=-3/10, or 1 and 7/10 total.
I hope this helps and you have a great day :)
