Answer

Explanation:

Step1: Count the amount of paint thinner in each can

There are 3 cans with $\frac{1}{2}$ cup each, 3 cans with $1\frac{1}{2}$ cups each and 1 can with 2 cups.

Step2: Calculate the total amount of paint thinner

The total amount is $3\times\frac{1}{2}+3\times1\frac{1}{2}+ 2$. First, $3\times\frac{1}{2}=\frac{3}{2}$, $3\times1\frac{1}{2}=3\times\frac{3}{2}=\frac{9}{2}$. Then $\frac{3}{2}+\frac{9}{2}+2=\frac{3 + 9}{2}+2=\frac{12}{2}+2=6 + 2=8$ cups.

Step3: Divide the total by the number of cans

We divide the total 8 cups by 7 cans. So the amount in each can is $\frac{8}{7}=1\frac{1}{7}$ cups.

Answer:

$1\frac{1}{7}$ cups
