Question

if a,12,16 and b are in continued proportion,find a and b

​

Answer 1

Answer:

it is given that

a,12,16 and b are in continued proportion

a/12=12/16=16/b

so,

a/12=12/16

by cross multiplication

16a=144

a=114/16=9

similarly

12/16=16/b

by cross multiplication

12b=16×16=256

b=256/12=64/3=21×3/3+1=21 1/3

therefore,a=9 and b=64/3 or 21 1/3
