Answer:
Step-by-step explanation:
a((100+50)/100)(100-50)/100
a(1.5)(.5)=0.75a
So a is larger than a(1.5)(0.5)
How much larger is a than 3a/4?
a/(3a/4)
a(4/3a)
a is 4/3 greater, so it does indicate a 33(1/3)% increase. Maybe they just want the fraction saying it is 1/3 greater or the difference of 0.25a
D
1/6
