What is the quotient of <br><img src="https://tex.z-dn.net/?f=2%20%5Cfrac%7B2%7D%7B7%7D%20%20%5Cdiv%20%20%5Cfrac%7B4%7D%7B7%7D%2

$2 \frac{2}{7}$ ÷ $\frac{4}{7}$

First, let's turn the first fraction into an improper fraction.

$\frac{16}{7}$ ÷ $\frac{4}{7}$

Since both of these fractions share the same denominator, we can drop the denominator and simply divide the numerators.

16 ÷ 4 = 4

The quotient = 4
