Question

One-third of a number is 5 less than half of the same number. What is the number?

Answer 1

`x = 30`

Explanation:

Let the number be `x` so that we have something to use to make an equation.
`x/2 -5 = x/3 " or " x/2 -x/3 = 5`

`xx 6:" " 3x - 30 = 2x`

`x = 30`

Check: `1/2 xx 30 = 15`
`1/3 xx 30 = 10`

`15-10 = 5`
