Answer:
1.25
Step-by-step explanation:
original price + markup = retail
The markup = original * markup percentage
original + original * markup percent= retail
Factor out the original
original( 1+ markup percent) = retail
original ( 1 + 60%) = 2
Change to decimal form
original ( 1+ .60) = 2
original ( 1.60) = 2
Divide each side by 1.6
original = 2/1.6
original =1.25
First step: flip the second fraction and change the sign from divide to multiply
(1/4)/(8/9)
(1/4)(9/8)
Second step: multiply across (as it can not be simplified)
1(9) = 9
4(8) = 32
9/32 is your answer
