Question

Find the third proportional to
a. 16 and 9 b. 0.04 and 0.3​

Answer 1

(a) 16 and 9

let the third proportional be x

now,

16 : 9 = 9 : x

16 × x = 9 × 9

16 × x = 81

x = 81 / 16

x = 5.4

(b) 0.04 and 0.3

let the third proportional be x

now,

0.04: 0.3 = 0.3 : x

0.04 × x = 0.3 × 0.3

0.04 × x = 0.09

x = 0.09/ 0.04

x = 2.25
