1. Answer: multiply both sides by the reciprocal

Explanation:

In order to isolate the variable, you need to multiply both sides by the reciprocal of the fraction so the numerator and denominator cancel out. For example:


(2)/(3)x=1\\\\\\\bigg((3)/(2)\bigg)(2)/(3)x=1\bigg((3)/(2)\bigg)\\\\\\x=(3)/(2)

2. Answer: multiply both sides by the divisor

Explanation:

In order to isolate the variable, you need to multiply both sides by the divisor so the whole number cancels out. For example:


(x)/(2)=1\\\\\\(2)(x)/(2)=1(2)\\\\\\x = 2
