Concept

Ratio in mathematics is defined as how many times something contains other.

For example

Given

1) 20 days

2) 72 hours

Find

Ratio of 20 days to 72 hours

Solution

As we know that 24 hours = 1 day

Using Unitary Method

24 hours = 1 Day

1 hour= 1/24

72 hours = (1*72)/24

72 hours = 3

So 72 hours equals to 3 days

Now we have to find ratio between 20 days and 3 days

Ratio = 20/3

= 20 : 3

The ratio of 20 days to 72 hours is 20 : 3
