Answer 1

Answer:

C

Step-by-step explanation:

Given: (A/3) = (B/4) = (C/5).

Let, (A/3) = (B/4) = (C/5) = k{Some constant}

Then:

(A/3) = K => A = 3K

(B/4) = k => B = 4k

(C/5) = k => C = 5k

Now,

A : B : C = 3K : 4K : 5K

             = 3 : 4 : 5

Hope it helps!

Answer 2

answer: option c

step-by-step explanation :

we know that a number will be 1 when both it's denominator and numerator are same as 2/2 = 1

if they all are equal so, it is easy to tell that they are either 0 or 1 as thier..

but according to this problem we can't take this rational number as 0.

so, answer is 3:4:5.
