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:
$\frac{4}{5} \times (x) = - 48$
We make both sides to have an x.
$\frac{4}{5} x = ( \frac{ - 48}{1} \times \frac{x}{1} ) \\ \\ \frac{4}{5}x = - 48x$
bring over the 5 to -48x
$4x = ( - 48x \times 5) \\ 4x= - 240 \\ x = \frac{ - 240}{4} \\ x= - 60$
to cross verify: 4/5 × (-60) = -48


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

Answer 2

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