Comparison of Numbers

Comparison of Numbers.

 We use symbols >, < and = to compare any two numbers

Which is smaller 20344 or 3241?

Number with more number of digits is a larger number.

Number with less number of digits is a smaller number.

3241 [4 digits] < 20344 [5 digits]

Which is greater 73652 or 56372 ?

Here, both the numbers have 5- digits. So the highest digit is to be compared to find the greater number.

Here 7 ten thousands is greater than 5 ten thousands.

Hence,

73652 > 56372

We read it as, seventy three thousand six hundred and fifty two is Greater than fifty six thousand three hundred and seventy two.

Which is smaller 54349 or 53449?

Since both are five digit numbers and the digits in the ten thousands place are equal, the numbers in the thousands place should be compared.

When we compare the thousands place, the first number has 4 Thousands and seconds one has 3 Thousand so the second number is the smaller number.

Hence.,

53449 < 54349

We read it as fifty three thousand four hundred and forty nine is less than fifty four thousand three hundred and forty nine.

For example:

 a) 54,689 < 54,869

b) 75,432 > 75,412

c) 45,327 < 45,321

To think : Find out which digits are compared in each example?

Try this
