Question

1 15 4 5 Find the value of x in each of the given proportions : (i) 0.9 :0.6 ::X:3 (ii) x:5:: 28:35 (iii) 1.6 :X :: 0.12 : 0.24 (iv) v) 16:x::x:25

please give the method too​

Answer 1

Answer:

(i) x = 4.5

(ii) x = 4

(iii) x = 3.2

(iv) x = 20

Step-by-step explanation:

Product of extremes = Product of means

a:y::z:w

w x a = y x z

in the fourth one, its equal. So, we have to do $\sqrt{x}$.
