Question

if A/3=B/4=C/5,THEN A:B:C=WHAT

Answer 1

Answer:

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

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

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

A = 3k

B = 4k

C = k

The ratio of A and B is  

$\frac { A } { B } = \frac { 3 k } { 4 k } = \frac { 3 } { 4 }$

The ratio of B and C will be

$\frac { B } { C } = \frac { 4 k } { 5 k } = \frac { 4 } { 5 }$

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

Answer 2

Answer:

A:B:C = 3:4:5

Step-by-step explanation:

Given $\frac{A}{3}=\frac{B}{4}=\frac{C}{5}$

Let $\frac{A}{3}=\frac{B}{4}=\frac{C}{5} = m$

Now ,

i ) $\frac{A}{3}=m$

$\implies A = 3m$---(1)

ii) $\frac{B}{4}=m$

$\implies B = 4m$---(2)

iii)$\frac{C}{5}=m$

$\implies C= 5m$---(3)

A:B:C = 3m:4m:5m

/* From (1),(2)& (3) */

Divide each term by m , we get

=> A:B:C = 3:4:5

Therefore,

A:B:C = 3:4:5
