Question

Beau’s recipe goes granola bars call for 3 1/2 of oatmeal . He only has 1/6 cup scoop. How many scoops of oatmeal will he need for the recipe?

Answer 1

Answer:

21 scoops

Step-by-step explanation:

We will divide the amount the recipe calls for, 3 1/2 cups, by the size of the scoop, 1/6 cup:

3 1/2 ÷ 1/6

Convert the mixed number to an improper fraction.  Multiply the whole number by the denominator and add the numerator; 3(2)+1 = 6+1 = 7; this makes it 7/2:

7/2 ÷ 1/6

To divide fractions, flip the second one and multiply:

7/2 × 6/1

42/2 = 21

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 number of cups of oatmeal that are called for the recipe are $3\dfrac{1}{2}.$

Solve the improper fraction $3\dfrac{1}{2}$ to obtain the proper fraction.

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

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

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

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

The 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.
