rachel teaches an oil - painting class. she has a can of paint thinner at each of the 7 easels in her studio. the graph shows how much paint thinner is left in each can. amount of paint thinner cups if rachel distributes all of the paint thinner equally among the 7 cans, how much will be in each can? $\frac{6}{7}$ cup $\frac{7}{8}$ cup 1 cup $1\frac{1}{7}$ cups
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
