Answer 2

Answer:

=> Compound Ratio = 20 : 21

Step-by-step explanation:

Given ratio:-

$5:7$ and $4:3$

As we have to find the compound ratio,  

Solution :

For ratios $m : n$ and $p : q$; the compound ratio is $(m \times p) : (n \times q).$

As we have,

=> $\frac{5}{7} =\frac{4}{3}$

It is expressed as $(m \times p) : (n \times q)$

=> $(5\times 4):(7\times 3)$

Simplifying it further, we get

=> 20 : 21

Hence, the compound ratio will be 20 : 21.
