Question

if a:b=3:2 and b:c=3:5,then a:b:c is

Answer 1

Answer:

The obtained ratio for A: B: C is 9 : 6 : 10

To find:

A: B: C = ?

Solution:  

Given :  

A: B = 3: 2 and B: C = 3: 5

To compare two ratios, we need to make one of the ratios equal. Here we had B term in both the ratios, so we are making two terms equal by making B equal.

Multiplying A: B i.e. 3: 2 by 3  

and B: C i.e. 3: 5 by 2 to bring the value of B at par, we get

A: B = 9: 6 & B: C = 6: 10

Hence, the value of A: B: C is obtained to be 9 : 6 : 10

 

Answer 2

Answer:

$A:B:C = 9:6:10$

Step-by-step explanation:

$A:B= 3:2 \:---(1)$

$B:C = 3:5 \:---(2)$

/* Now , multiply equation (1) by 3 , and equation (2) by 2, we get

$A:B = 9:6\:---(3)$

$\:\:\:B:C = 6:10\:--(4)$

\* From (3) and (4), we get

$A:B:C = 9:6:10$
