Question

Which of the following uses the reciprocal property to rewrite $\frac{x}{5}$= $\frac{72}{4}$?

Answer choices are in the attachments

Answer 1

$\frac{x}{5} = \frac{72}{4} \\ \\ x \times 4 = 72 \times 5 \\ \\ 4x = 360 \\ \\ x = \frac{360}{4} \\ x = 90$

Answer 2

Reciprocal is flipping an equation so x/5=72/4 to flip your answer would be the second answer choice from the top. Cause all your doing is flipping the equation but not changing the numbers around.
