Hello there.

Tyrone mixed 7/12 quart of red paint with 1/12 quart of yellow paint how much paint does Tyrone have in the mixture?

Answer: In this question you need to add together the fractions provided.
The sum would look like this:
 $\frac{7}{12}$ + $\frac{1}{12}$ =
Since the denominators are the same , it is simple to add.
All you need to do is 7 + 1 = 8.
Therefore the end result after solving would look like.
 $\frac{7}{12}$ + $\frac{1}{12}$ = $\frac{8}{12}$ .
Tyrone has 8/12 quarts of paint.
