Answer

60

Work Step by Step

In this problem, we are dividing by a fraction. However, we are never supposed to divide by a fraction. Rather, we must multiply by the reciprocal of the fraction. The reciprocal of a fraction is that fraction with the numerator (top of the fraction) and denominator (bottom of the fraction) switched. Thus, we simplify to find: $-54\div(-.9)=-54\times(-10/9)=60$ Note, a negative times a negative is a positive.
