Question

If A : B = 5 : 8 and B : C = 4: 3, A : B : C =

Answer 1

Given that:- $A : B = 5 : 8$

and $B : C = 4: 3$

To find :- The ratio of $A : B : C$

Now, multiply each term of the ratio $4:3$ by $\frac{8}{4}=2$ to make its first term equal to 8,

$=>B:C=4*2:3*2=8:6$

$=>A:B:C=5:8:6$

Therefore, the ratio for $A:B:C=5:8:6$

Answer 2

As per data given in the question,

We have to convert the individual ration in form of composite ratio.

From the given data,

We have,

A:B = 5:8

B:C = 4:3

For converting the above ratio in single ratio let us observe the given ratio.

As we see the B is common in both the equation,

So, equalizing the ration of B in both the equation.

We have to multiply the second equation by 2

So,

We will get the new equation as,

$A:B = 5:8 -------(1)\\B:C = (4\times 2):(3\times 2) = 8:6\\Hence,\\The\: equivalent\: ratio\: will\: be,\\A:B:C = 5:8:6$
