So, 42.875 < 423.95     

 

First of all, we compare the numbers before decimal points.

If they are less than or greater than,

Then the numbers are also less than or greater than

 

But….

What if the numbers before Decimal points are equal?

 

Compare 23.75 & 23.89

Comparing digits before decimal point

Comparing decimals - Part 2

So, we compare digits after decimal point

Comparing decimals - Part 3

 

So,

  23.75 < 23.89

 

Let’s take another example

 

Compare 4.08 & 4.076

 

Here, number of digits of 4.08 and 4.076 is not same

 

Writing

  4.08 = 4.080

So, we need to compare

  4.080 & 4.076

 

Comparing digits before decimal point

Comparing decimals - Part 4

 

So, we compare digits after decimal point

Comparing decimals - Part 5

 

So we compare the next digit

Comparing decimals - Part 6

So,

  4.08 > 4.076
