You cannot put these fractions in simplest form, but instead a mixed number.
You can put any improper fraction into a mixed number by dividing the numerator by the denominator.
So, 7/3 can be divided. 7 divided by 3 is equal to 2 with a remainder of 1. When dividing to make a mixed number, take the remainder and put it as a fraction with the denominator being the divisor of your problem. Ex. 2 w/ a remainder of 1 would turn in to 2 1/3.
This same process applies for the other 2 as well.
