Answer:

$\frac{2}{7}$

Step-by-step explanation:

$\frac{7}{2}$ ÷ $\frac{49}{4}$ needs to be flipped and multiplied.

It will become $\frac{7}{2}$ · $\frac{4}{49}$ .

Simplify the fractions by replacing 7 with 1 and 49 with 7, since 7 is 1/7 of 49. Then, turn the 2 into a 1 and the 4 into a 2, since 2 is half of 4.

You will be left with 1 · $\frac{2}{7}$ , which equals $\frac{2}{7}$
