Question

If A = 3B = 5C, find A:B:C.​

Answer 1

Answer:

Step-by-step explanation:

A=3B=5C=k

a=k

b=k/3

c=k/5

so

k:k/3: k/5

now multiply whole by 15

15k:5k:3k

now divide by k

so

15:5:3

Answer 2

Answer:

15:5:3

Step-by-step explanation:

A=3B=5C

So, A=3B…(i)

And, 3B=5C

or, C=3B/5…(ii)

So, A:B:C = 3B:B:3B/5[ from (i) and (ii)]

=3:1:3/5(Cancellation of B)

= 15:5:3

Hence, The value of A:B:C is 15:5:3( answer).
