Problem

$(a)$ Joyce has two identical jars. The first jar is $\frac{3}{4}$ full of water and contains $300$ mL of water. The second jar is $\frac{1}{4}$ full of water. How much water, in mL, does the second jar contain?

Solution

Since $\frac{3}{4}$ of a jar is $300$ mL, and because the first jar has 3 times as much water as the second jar ($\frac{\frac{3}{4}}{\frac{1}{4}}=3$), then the second jar has $\frac{300}{3}=\boxed{100}$ mL of water.
