Question

the circle below represents a whole, or 1. use subtraction to determine the unknown part of the circle.

Explanation:

Step1: Find a common denominator

The common - denominator of 7 and 14 is 14. Rewrite $\frac{4}{7}$ as $\frac{8}{14}$ ($\frac{4\times2}{7\times2}=\frac{8}{14}$).

Step2: Set up the subtraction

The whole circle is 1, which can be written as $\frac{14}{14}$. We subtract the known parts $\frac{8}{14}$ and $\frac{1}{14}$ from $\frac{14}{14}$. The expression is $\frac{14}{14}-\frac{8}{14}-\frac{1}{14}$.

Step3: Perform the subtraction

$\frac{14 - 8-1}{14}=\frac{5}{14}$.

Answer:

$\frac{5}{14}$
