Question

1 Jessica took 1/3 pound of pretzels and placed them equally into 3 bowls. How much will be in every bowl?

Answer 1

To solve the exercise, take the number of pretzels and divide it by 3. So,

$\begin{gathered} \text{ Number of pretzels in each bowl}=\frac{\frac{1}{3}}{3} \\ \text{ Number of pretzels in each bowl}=\frac{\frac{1}{3}}{\frac{3}{1}} \\ \text{ Because }3=\frac{3}{1} \end{gathered}$

Now, to divide fractions you operate like this:

$\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot d}{b\cdot c}$

Then, you have

$\begin{gathered} \text{ Number of pretzels in each bowl}=\frac{\frac{1}{3}}{\frac{3}{1}} \\ \text{ Number of pretzels in each bowl}=\frac{1\cdot1}{3\cdot3} \\ \text{ Number of pretzels in each bowl}=\frac{1}{9} \end{gathered}$

Therefore, in every bowl will be 1/9 pound of pretzels.
