Thanks for asking ❤

Step-by-step explanation:

Thus the value of A: B: C is 3: 4: 5

To find:

The ratio of A, B and C

Solution:

Let the given terms be

\frac { A } { 3 } = \frac { B } { 4 } = \frac { C } { 5 } = k3A=4B=5C=k

Comparing the terms with the value k, we get the following,

A = 3k

B = 4k

C = k

The ratio of A and B is  

\frac { A } { B } = \frac { 3 k } { 4 k } = \frac { 3 } { 4 }BA=4k3k=43

The ratio of B and C will be

\frac { B } { C } = \frac { 4 k } { 5 k } = \frac { 4 } { 5 }CB=5k4k=54

Thus, the value will be

A: B =3: 4

B: C = 4: 5

A: B: C = 3: 4: 5

Thus, the value of A: B: C will be equal to 3: 4: 5
