Round your factors to the nearest 10's, 100's 1000's, etc. Then multiply. You should be able solve the problem more or less in you head. If you need to use a pen and paper, you must round to and even higher place. When rounding, if the place your rounding ends in 1-4, you round down. 5-9= round up. For example: 14 rounded to the nearest 10 =10. 16 rounded to the nearest 10=20. 123 rounded to the nearest 100= 100. 191 rounded to the nearest hundred= 200.
rounding whole numbers and decimals
No because whole numbers are integers without decimals or fractions
No because whole numbers are integers that do not have decimals or fractions attached to them.
Whole numbers contain no fractional part as do decimals
Decimals are real numbers. Furthermore, integers and whole numbers are the same thing.

Weird
Decimals include a fractional part, represented by digits to the right of the decimal point, while whole numbers only have a whole part, represented by digits to the left of the decimal point. Whole numbers can be positive or negative, while decimals can also be fractions or mixed numbers. Additionally, whole numbers are used to count while decimals are used for measurement and precision.
Decimals separate whole numbers from fractions.
Whole numbers are positive numbers and there are no fractions or decimals.
One way they are different is that decimals are "parts of a whole" not necessarily a whole.
All whole numbers are decimal numbers.
