If a:b::c:d then ad= bc. Therefore, 0.75:x::5:8 implies 5x=8*0.75 i.e., x=6/5=1.20.

The answer is 5:1. SOL :- x : y=9 : 10==> 10 x=9 y==> 5 x = 9 y/2, substituting 9y/2 for 5x in ( 5 x + 3 y) : (5 x - 3 y) gives 5: 1

(B/C ) * (C/D)= (6/7) * (14/15) => B/D = 4/5 => (A/B)*(B/D)=(4/5)*(4/5) => A/D = 16/25.

If x : y : z, show that x : z = (square of x) : (square of y)?

Shambhavi S.

As we know that , x:y:z , this implies that, y^2=x*z. Simplifying x:z=x^2:y^2, we get, y^2=x*z, which is the same as above. Thus, they are equal.
