Question

Find the fourth proportional to :
(1) 8.32.17
(ii) 8.1, 1.2, 2.7​

Answer 1

Step-by-step explanation:

Find the fourth proportional to :(i) 8.32.17

let fourth proportion be a

8.32.17,a are in proportion

product of extremes= product of means

8 x a = 32 X 17

a = 32 x 17 / 8

a = 68

Find the fourth proportional to : (ii) 8.1, 1.2, 2.7

let fourth proportion be a

8.1, 1.2, 2.7, a are in proportion

product of extremes= product of means

8.1 X a = 1.2 X 2.7

a = 1.2 X 2.7/8.1

a=0.4
