Question

calculate the ratio of the second term to the first term, and express the answer as a decimal value. State the percent increase or decrease

a. 80,60
b. 40,45
c. 88,198
D, 36,32
e. 110,96.8
f. 63,100.8

Answer 1

60:80
60/80=0.75, 60=75% of 80
60:80 = 0.25:0.75
60+x=80
x=20
20/60 = (100/3)%, 20 = (100/3)% of 60
(100%) + (100/3)%= (400/3)%
therefore 60:80= 0.25:0.75, the change is + (400/3)%
