Compare numbers up to millions :
Compare numbers up to millions is the topic in which we are going to learn how to compare two numbers.
To compare two values that are not the same, we can write an inequality.
Inequalities can be expressed using greater than (>) or less than (<) symbols.
Before going to compare two or more whole numbers, we have to know about what is whole numbers.
The set of all non negative integers is whole numbers.
That is,
W = { 0, 1, 2, 3, 4, .........................}
Example 1 :
Use <, > or = to make the following statement true
16807 ____ 16809
Solution :
By observing the given numbers, both are having same number of digits. So we have to compare those numbers by comparing their place values.
Example 2 :
Use <, > or = to make the following statement true
74,684 ____ 74,686
Solution :
By observing the given numbers, both are having same number of digits. So we have to compare those numbers by comparing their place values.
Example 3 :
A toy factory manager monitored the number of toys made each month.
Month |
Number of toys |
July August September November |
31,679 36,128 31,627 36,127 |
In which month did the factory make the most toys?
Solution :
From this we can decide that, they have produced more number of toys in the month of August.
