Step 1: State the given in the question
Given for example, the population of China estimated at 1.393 billion and the population of India estimated as 1.353 billion
Step 2: State what to be determined
We are to state all the ways to campare the two large numbers
In other to achieve this, there are three basic ways to compare large numbers.
These basic ways are:
1) Write the number in place value chart
2) Compare the digits starting with the greatest place value
3) If the digits are the same, compare the digits in the next place value to the righ. Keep compairing digits with the same place value until you find digits that are different.
Step 3: Use the three ways of comparison to compare the two given numbers
Let us see how these basic ways applies to the given numbers as example
Given two numbers
1.393 billion and 1.353 billion
1) Write the number in place value chart. This is as shown below:
2) Compare the digits starting with the greatest place value
From the place-value chart above, it can be observed that the greatest place value for the two numbers is unit of billions. The digits at billion (that is 1) are the same
3) If the digits are the same, compare the digits in the next place value to the righ. Keep compairing digits with the same place value until you find digits that are different.
From chart, we could observe that
b) The digits at hundreds of millions (that is 3) are the same
c) The digits at tens of millions (that is 9 and 5) are different
Since the value of 9 is greater than 5, then we can conclude that 1.393 billion is greater than 1.353billion
ANSWER SUMMARY
The Three ways to campare the two large numbers are
1) Write the number in place value chart
2) Compare the digits starting with the greatest place value
3) If the digits are the same, compare the digits in the next place value to the righ. Keep compairing digits with the same place value until you find digits that are different.
