Question

How do you solve `b/4<3`?

Answer 1

`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

`color(red)cancel(4xx) b/cancel4 < color(red)(4xx) 3`

`b <12`

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