Question

Three less than fifty percent of a number is equal to one-half. What is the number?

Answer 1

`7`

Explanation:

Let the number be `x`. So, we have the equation:

`50%*x-3=0.5` (three less than fifty percent of a number is equal to one-half)

`:.0.5x-3=0.5`

`0.5x=3+0.5`

`=3.5`

`x=3.5/0.5=7`
