Exercise 35 Page 42

When dividing numbers of opposite signs, the quotient is always negative.

- 0.9

Practice makes perfect

Let's begin by rewriting the division as a fraction. -8.1÷9 ⇒ - 8.1/9Notice that the numerator and denominator have opposite signs. Because the quotient of a negative number and a positive number is always negative, we can move the negative sign in front of the fraction. - 8.1/9 = - 8.1/9 We are now going to simplify the quotient further.

- 8.1/9

ExpandFrac

a/b=a * 10/b * 10

- 81/90
