Question

a:27/64=3./4:a.value of a

Answer 1

a:27/4 = 3/4 : a

For ratios the rule is product of extremes = product of means

So,

a*a = 27/4 * 3/4

⇒ a²= 81/4

⇒a = √(81/4)

⇒a=9/2 ~ 4.5

Answer 2

by the rule of product of means = product of extremes .

so .... a*a = 27/64*3/4

a^2 = 81/256

a = √81/256

a = 9/16

hope this helps you.
