- 6

Practice makes perfect

Let's begin by rewriting our division as a fraction. -84÷14 ⇒ - 84/14Notice that the numerator and denominator have opposite signs. Since the quotient of a negative and positive number is always negative, we can move the negative so that it is in front of the fraction. - 84/14 = - 84/14 Use the fact that 84 can be decomposed into 6* 14 to help us simplify this quotient.

- 84/14
