Perhaps there is a conversion problem. A whole number such as homework would be listed as 1. The question of how much is left works out in this manner.
The total home work equals 1. The amount that has been compleated is 3/4.
If you set it up as fractions, the total or 1 is written as 1/1.
The amount completed is 3/4.
Therefore you subtract the amount completed from the total amount to be completed:
1/1 - 3/4
To complete this equation, you first need to find a common denominator or number for the bottom part of the fraction:
1/1 = 4/4
So then you, use the fractions with the same denominator and complete the equation:
4/4 - 3/4
Once you complete this equation you will arrive at the answer:
4/4 - 3/4 = 1/4
I hope this helps.
