Question

If A:B:C=3:4:5 then what A/C:B/A:C/B

Answer 1

Step-by-step explanation:

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

A/C=3/5

B/A=4/3

C/B=5/4

3/5:4/3:5/4

Answer 2

$36:80:75$ is the ratio of $A/B:B/A:C/B$

Step-by-step explanation:

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

$A=3x$

$B=4x$

$C=5x$

Then find the ratio for

$\frac{A}{B}=\frac{3}{5}$,

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

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

then divide all three

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

take L.C.M of all three the denominators $(5,3,4))=60$

$A/B:B/A:C/B$= $3\times 12:4\times 20:5\times 15$

                          = $36:80:75$
