Question

If a : b and c : d are two ratios , then compound ratio of those two ratios is

Answer 1

Step-by-step explanation:

The compound ratio of a : b and c : d is

= a * c : b * d

= ac : bd

Answer 2

Given Ratios:-

a : b and c : d

∴ Compound Ratio will be a × c : b × d

Example

3a : 2b , 2m : n

Here We Have 2 Ratios

So using Compound Ratio Formula We need To Solve It.

So, Required Compound Ratio =

$= (3a × 2m) : (2b × n) \\ \\ = \frac{6am}{2bn} \\ \\ = \frac{3am}{bn} \\ \\ = 3am : bn$
