Hello there,
Okay so the question is asking us to subtract the two mixed numbers, 6 3/5 - 2 4/5, from each other...
The first step would be to change the mixed numbers to improper fractions:
Now we need to make sure that the denominators are the same and in this case they are.
Simply subtract 14 from 33 and you would get 19 and the denominator stays the same so you would get 19/5.
The answer to the 6 3/5 - 2 4/5 would be 3 4/5.
Hope I helped,
Amna
