44/22 = 2 so the decimal point should be placed after the first digit (which is a 1).
One decimal place. 3.9 is the quotient.
4*5 = 20 so the answer should be around 20.
If you have no clue about how decimals work then getting an estimate for the answer gives you an order of magnitude which can help in placing the decimal. But if you are even a bit clued up, estimating will not be necessary.
When you divide by ten the decimal point moves one place to the left.
An estimate will give an indication of the order of magnitude of the answer. The decimal point determines the order of magnitude and so, if the two are in agreement, then the decimal point has been placed in the right place. However, if you did your arithmetic properly then there would be no need to do the extra calculations required for an estimate.
One decimal place. 3.9 is the quotient.
An estimation, like 600 divided by 6, will show you that the answer should be around 100, not 10 or 1000.
0.6705
0.6705
An estimation, like 600 divided by 6, will show you that the answer should be around 100, not 10 or 1000.
It could be 0.2 to one decimal place.
5.67
0.8 to one decimal place or 1 as a whole number.
You can use estimation and place value to help you figure out where to place the first digit.
If you were doing it as a long division (in standard layout) then above the 6 - just after the decimal point.
0.012
4 as a whole number or 4.2 to one decimal place.
