Question

Four-fifths of a number is -48

Answer 1

So we write out the numbers on an equation first.
Assuming X is the unknown number, the formula as follows:

`(4)/(5) * (x) = - 48`
We make both sides to have an x.

`(4)/(5) x = ( ( - 48)/(1) * (x)/(1) ) \\ \\ (4)/(5)x = - 48x`
bring over the 5 to -48x

`4x = ( - 48x * 5) \\ 4x= - 240 \\ x = ( - 240)/(4) \\ x= - 60`
to cross verify: 4/5 × (-60) = -48


Answer : Four-fifths of (-60) is -48

Answer 2

-48:4=-12
-12*5=-60
