natulia [17]

\boxed{21} scoops of oatmeal will he need to complete the recipe.

Further explanation:

Given:

Beau's recipe from granola bars calls for 3\dfrac{1}{2} cups of oatmeal.

He only is \dfrac{1}{6} scoop.

Explanation:

The cups of oatmeal called for the recipe is 3\dfrac{1}{2}.

Solve the improper fraction 3\dfrac{1}{2}.

\begin{aligned}{\text{Fraction}}&=\frac{{2 \times 3 + 1}}{2}\\&=\frac{{6 + 1}}{2}\\&=\frac{7}{2}\\\end{aligned}

The Beau has \dfrac{1}{6}{\text{ scoop}}.

The number of scoops required to complete the recipe can be obtained as follows,

\begin{aligned}N&=\frac{{{\text{total cups of oatmeal}}}}{{{\text{the fraction of scoop Beau has}}}}\\&=\frac{{\frac{7}{2}}}{{\frac{1}{6}}}\\&= \frac{7}{2} \times6\\&=\frac{{42}}{2}\\&= 21\\\end{aligned}

Number of scoops required to complete the oatmeal is 21{\text{ scoops}}.

Therefore, \boxed{21} scoops of oatmeal will he need to complete the recipe.
