So we write out the numbers on an equation first.
Assuming X is the unknown number, the formula as follows:
[tex] \frac{4}{5} \times (x) = - 48[/tex]
We make both sides to have an x.
[tex] \frac{4}{5} x = ( \frac{ - 48}{1} \times \frac{x}{1} ) \\ \\ \frac{4}{5}x = - 48x[/tex]
bring over the 5 to -48x
[tex]4x = ( - 48x \times 5) \\ 4x= - 240 \\ x = \frac{ - 240}{4} \\ x= - 60[/tex]
to cross verify: 4/5 × (-60) = -48
Answer : Four-fifths of (-60) is -48
