well first you need to convert the mixed numbers into improper fractions like so
3 1/5 would be 16/5 because 3 times 5= 15+1=16 the same with 1 4/5 but you can do this one a bit differently like so- 1=5/5 + 4/5 = 9/5 So now we move on to the subtraction part of the problem. 16/5-9/5= 7/5 because we know 16-9=7 But now you got to convert this improper fraction back into a proper fraction: 7/ 1 2/5 because 5 goes into 7 one time with a remainder of 2 (2/5) So the answer would be: Ethan read 1 2/5 more books than he did this week.
