Question

If 3A=5B=6C, find A:B:C

Answer 1

Answer:

10 : 6: 5

Step-by-step explanation:

Let all these be equal to a constant 30k(any constant can be taken, i took 30 for convenience).

3A = 5B = 6C = 30k.

It means,

A = (30k)/3 = 10k

B = (30k)/5 = 6k

C = (30k)/6 = 5k

Hence,

A : B : C = 10k : 6k : 5k

              = 10 : 6 : 5

Answer 2

Answer:

3A = 5B = 6C

from here

we get

B = 3/5A

C = 1/2A

then A:B:C

= A: 3/5A:1/2A

= 1:3/5:1/2

take lcm of 5 and 2 i.e. 10

multiply is to the numerator

then we get

10:6:5

so the required ratio is 10:6:5
