Exercise 66 Page 71

What happens when you divide two negative numbers?

60

Practice makes perfect

First, note that we can rewrite the division as a fraction. -54÷-0.9 ⇒ - 54/-0.9 Notice that, in the fraction form, the numerator and the denominator are both negative. Since the quotient of two negative numbers is always positive, we can remove both negatives. Next, we are going to expand the fraction to help us further simplify the result.
