Question

Find the fourth proportional of 1.2,24,0.02

Answer 1

Answer:

let the fourth person be x

=> 1.2 : 24 :: 0.02 : x

we know that product of extremes is equal to product of means

here extreme terms are 1.2 and x and

middle terms are 24 and 0.02

=> 1.2 × x is equal to 0.02 × 24

=> x = (0.02×24)/1.2

=> x = 0.4

=> 0.4 is the fourth proportion
