Exercise 4 Page 42

What happens when you divide a negative number by a negative number?

9/8

Practice makes perfect

When dividing fractions, we multiply by the inverse of the second fraction. Recall that the product of two negative factors is always positive.

(- 9/10) ÷ (- 4/5)
(-9/10) ÷ (-4/5)
-9/10 * 5/-4
(-9)5/10(-4)
- 9* 5/10(-4)
- 9* 5/- 10* 4
- 45/- 40
45/40
9/8

The quotient is equal to 98.
