Question

One-half of a number is 8. Find the number.

Answer 1

Number is 48
People are giving the right answer, but with no explanation. So here's a convenient method and dictionary to follow.

Always work backwards.
"Of" - multiply
"And" - add
"More than" - add
"Less than" - subtract (be sure to work backwards, so you do (2nd number) - (1st number))
"A number" - variable (usually x)
"Is" - equals

So let's translate that sentence. Working backwards:

"A number" is x
"Of" is *
"Half" is 1/2
"Less than" is -
"Eight" is 8
So we have x*1/2 - 8, or x/2 - 8
