Answer 2

Answer:

Taking the LCM of 3 , 2 & 5 , we get 30 .

Therefore,

30A10=30B15=30C6

Dividing all by 30 , we get,

A10=B15=C6=k (say)

A10 =k

=>A=10k

B15 =k

=>B=15k

C6 =k

=>C=6k

Now,

A:B:C=10k:15k:6k

Removing k ,

A:B:C=10:15:6

Here is the shortcut to find the ratio A:B:C , given 3A=2B=5C.

All you need to do is find A,B & C independently.

To find A:

Multiply the coefficients of B & C

That is, 2 x 5 = 10, this is the value of A.

To find B:

Multiply the coefficients of C & A

That is, 5 x 3 = 15, this is the value of B.

To find C:

Multiply the coefficients of A & B

That is, 3 x 2 =6, this is the value of C.

Therefore, A: B:C = 10:15:6

3A=2B=5C

Taking the LCM of 3, 2 & 5, we get 30.

Therefore,

30A/10 = 30B/15 = 30C/6

Dividing all by 30, we get,

A/10 = B/15 = C/6 = k(say)

A/10 = k => A = 10k

B/15 = k => B = 15k

C/6 = k => C = 6k

Now,

A : B : C = 10k : 15k : 6k

Removing k,

A : B : C = 10 : 15 : 6
