# How do you solve b/4<3 ?

Sep 2, 2016

$b < 12$

#### Explanation:

Get rid of the denominator by multiplying both sides by 4.

4 is a positive number. It has no effect on the sign

$\textcolor{red}{\cancel{4 \times}} \frac{b}{\cancel{4}} < \textcolor{red}{4 \times} 3$

$b < 12$

[If you do multiply or divide by a negative number, the inequality sign changes around. ]
