Beau's recipe for granola bars calls for 3 1/2 cups of oatmeal. He only has a 1/6 cup scoop. How many scoops of oatmeal will he
Drupady [299]

There will be \boxed{\bf 21} scoops of oatmeal to complete the recipe.

Further explanation:

Given that Beau’s recipe of granola bars contains 3\frac{1}{2} cups of oatmeal.

Beau’s has only \frac{1}{6} cup scoop.

Our aim is to find the number of scoops of oatmeal Beau’s needed to complete the recipe for granola bars.

Total cups of oatmeal are 3\frac{1}{2}.

First we have to convert the total cups of oat meal to proper fraction.

\begin{aligned}\text{Cups of oatmeal for the recipe}&=\dfrac{(3\cdot 2)+1}{2}\\&=\dfrac{6+1}{2}\\&=\dfrac{7}{2}\end{aligned}  

There is only \frac{1}{6} cup scoop.  

Since there are \frac{7}{2} cups of oatmeal and \frac{1}{6} cup scoop, therefore, number of scoops required to complete the meal are calculated as follows:

\begin{aligned}\text{Number of scoops required}&=\dfrac{\frac{7}{2}}{\frac{1}{6}}\\&=\dfrac{7}{2}\cdot 6\\&=7\cdot 3\\&=21\end{aligned}  

The total number of scoops is obtained in whole number; therefore, this is our final answer.

Therefore, \boxed{\bf 21} scoops of oatmeal are needed by Beau’s to complete the recipe of granola bars.
