Step-by-step explanation:

It is given that:

Beaus recipe for granola bars calls for 3 1/2 cups of oatmeal.  

i.e. the cups of oatmeal required is:

Also, he has:

$\dfrac{1}{6}\ \text{cup scoop}$

This means that:

$\text{Number of scoops of oatmeal he need}=\dfrac{\text{Number of cups of oatmeal}}{\text{Number of cup scoop he has}}\\\\i.e.\\\\\text{Number of scoops of oatmeal he need}=\dfrac{\dfrac{7}{2}}{\dfrac{1}{6}}\\\\i.e.\\\\\text{Number of scoops of oatmeal he need}=\dfrac{7\times 6}{1\times 2}\\\\i.e.\\\\\text{Number of scoops of oatmeal he need}=21\ \text{scoops}$

Answer 2

$\boxed{21}$ number of 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,

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

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

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