Question

if 3A = 4B= 5C = ,find A :B : C.​

Answer 1

Answer:

Hi friend!!

Let 3A = 4B = 5C = x

3A = x

A = x/3

4B = x

B = x/4

5C = x

C = x/5

A : B : C = x/3 : x/4 : x/5

LCM is 60

→ = 20x/60 : 15x/60 : 12x/60

→ = 20 : 15 : 12

A : B : C = 20 : 15 : 12

Hope it helps..

Answer 2

Answer:

20:15:12

Step-by-step explanation:

Given :

• 3A = 4B= 5C

L.C.M. of 3,4 and 5 is 60

Divide 3A = 4B= 5C by 60.

therefore

$\frac{A}{20} = \frac{B}{15} = \frac{C}{12}$

hence

$A :B : C = 20:15:12$
