-48/60 can be reduced to lowest terms by removing the common factor of 12. It can be made to have a denominator of 25 by adding a common factor of 5.

`-(48)/(60)=-(4\cdot12)/(5\cdot12)=-(4)/(5)\\\\=-(4\cdot5)/(5\cdot5)=\boxed{-(20)/(25)}`

Alternatively, the numerator of the desired fraction can be found by multiplying the given fraction by the desired denominator.

numerator = 25×(-48/60) = -1200/60 = -20

new fraction = -20/25
