Question

Amanda and Joyce spent 3 1/3 hours at the lake. For 1/3 of that time, they went fishing. What equation can be used to find the amount of time they spent fishing?Add, subtract, divide, or multiply?

Answer 1

Amanda and Joyce spent 3 1/3 hours at the lake.

For 1/3 of that time, they went fishing. To find the time spent fishing, we multiply both fractions:

$3\frac{1}{3}\cdot\frac{1}{3}$

We must express the mixed fraction as an improper fraction as follows:

$3\frac{1}{3}=3+\frac{1}{3}=\frac{3\cdot3+1}{3}=\frac{10}{3}$

Now we use the following equation to find the amount of time they spent fishing:

$\frac{10}{3}\cdot\frac{1}{3}=\frac{10}{9}$

They spend 10/9 hours fishing, we found that by multiplyingT
