A. 150% increase
B. 150% decrease
C. 50% decrease
D. 50% increase

During a special sales event, the dealership offers a 10%
discount off of the retail price ($15840). After the discount, how much will
a customer pay for this vehicle?

How to find out the answer to the problem,
-3/4 ÷ -1/8=

Answers

Answer:

Step-by-step explanation:

Dividing a negative by a negative will get you a positive result, so we can treat these fractions as positive numbers. To divide fractions, we take the reciprocal of the fraction we're dividing by and it'll be multiplied by the first fraction. To multiply fractions, we multiply numerator with numerator and denominator with denominator.

-3/4 ÷ -1/8 = 3/4 ÷ 1/8 = 3/4 * 8/1 = 24/4 = 6
