6. In 2010, Sacramento, California, received 23 inches in annual precipitation. In 2011, the city received 17 inches in annual precipitation. In which year was there more precipitation?
1. Answer :
Let us locate the two whole numbers 3 and 6 on a number line and mark them.
Here, 6 comes to the right of 3.
Therefore 6 is greater than 3.
And 3 comes to the left of 6.
Therefore 3 is smaller than 6.
2. Answer :
Let us locate the two whole numbers 6 and 9 on a number line and mark them.
Here, 9 comes to the right of 6.
Therefore 9 is greater than 6.
And 6 comes to the left of 9.
Therefore 6 is smaller than 9.
3. Answer :
Since the given numbers are three digit numbers, instead of using number line, we can compare the given numbers by comparing the digits in hundreds place, tens place and ones place.
In 625 and 628, we have the same digit in hundred place and tens place. So compare the digits in tens place.
The digit in one place of 625 is 5 and 628 is 8.
Since 8 is greater than 5, 628 is greater than 625.
4. Answer :
We can compare the given numbers by comparing the digits in hundreds place, tens place and ones place.
In 870 and 869, we have the same digit in hundreds place.
The digit in tens place of 870 is 7 and 869 is 6.
Since 7 is greater than 6, 870 is greater than 869.
5. Answer :
We can compare the given numbers by comparing the digits in hundreds place, tens place and ones place.
In 5390 and 5388, we have the same digit in thousands place and hundreds place.
The digit in tens place of 5390 is 9 and 5388 is 8.
Since 8 is smaller than 9, 5388 is smaller than 5390.
6. Answer :
Locate the two whole numbers 23 and 17 on a number line and mark them.
23 is to the right of 17 on the number line.
This means that 23 is greater than 17.
We can write the above situation in terms of inequality as 23 > 17.
17 is to the left of 23 on the number line.
This means that 17 is less than 23.
We can write the above situation in terms of inequality as 17 < 23.
There was more precipitation in 2010.
