Question

Divide the sum of 5/21 and 4/7by their difference​

Answer 1

Answer:

$\frac{17}{7}$

Step-by-step explanation:

sum = $\frac{5}{21} +\frac{4}{7}$

sum = $\frac{5}{21} +\frac{12}{21}$

sum = $\frac{17}{21}$

difference =$\frac{4}{7}- \frac{5}{21}$

difference =  $\frac{12}{21}-\frac{5}{21}$

difference = $\frac{7}{21}$

divide = $\frac{17}{21}$ ÷ $\frac{7}{21}$

divide = $\frac{17}{7}$
