-0.3 is the same as -3/10. Thus, we are asked to find: 75$\div$(-3/10). 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: 75$\div$(-3/10)=75$\times$(-10/3)=-250 Note, the answer is negative, for a negative times a positive or a positive times a negative is a negative.
