A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. Adding zeros after the decimal point is wrong because they imply a degree of accuracy (significant figures) for which there is no justification.
So a whole number is [usually] a decimal number and there is no dependency on decimal places.

How do you divide 376 by 93.01?
To divide 376 by 93.01, you change the devisor from a decimal to a whole number. Since 93.01 is the devisor, you move the decimal two places to the right to make it a whole number. It is now 9301. Then the same thing you do with the devisor you also do with the dividend. So since you move the decimal two places to make the devisor a whole number, you now have to move the decimal two places on the dividend. Remember, if you do not see a decimal in a number, it is understood to be behind the last digit. Therefore, in 376, the decimal would be understood to be behind the 6 which is the last digit. So to move the decimal two places on the dividend you just add two zeros, making it 37600. So now you are dividing two whole numbers. 37600 divide by 9301. The answer is 4,042 and you round it off to 4.02.

What do you do when there is a decimal on the outside of division house?
To divide decimal numbers:If the divisor is not a whole number, move decimal point to right to make it a whole number and move decimal point in dividend the same number of places.Divide as usual. ...Put decimal point directly above decimal point in the dividend.Check your answer.
What difference does it make if the decimal is placed before or after the number?
If the number is before the decimal, it is a whole number. The numbers after the decimal represent fractions of whole numbers. For example if you had to work 8.5 hours, you would work 8 whole hours plus one half hour.
How do you make a decimal into a whole number?
If every decimal could be made into a whole number, we wouldn't needdecimals at all, and the companies that manufacture the points would beout of business.The reason for wrtiting a number as a decimal is usually that it isn't awhole number, and it can't be written as one.
How do you make .20 as a whole number?
To express .20 as a whole number, you would multiply it by 100 to shift the decimal two places to the right. This would give you 20 as a whole number. Converting a decimal to a whole number involves removing the decimal point by multiplying the decimal by the appropriate power of 10.

Convert to fraction notation?
Write a fraction with the decimal number as the numerator and 1 as the denominator. Move the decimal point in the numerator to the right whatever number of places required to make it a whole number. Add the same number of zeros to the right of the 1 in the denominator as the decimal point was moved. Reduce if possible by dividing both members by the same whole number. Example: 0.125 = .125/1 = 125/1000 = 1/8
How do you divide a decimal by a decimal?
Make the divisor a whole number by moving the decimal point to the right and move the decimal point in the dividend to the right the same amount; now do the division. For example to divide 19.67 by 3.5: to make 3.5 a whole number, move decimal point 1 place to the right to give 35, so move decimal point of 19.67 to the right one place to give 196.7 Now do 196.7 divided by 35 to give 5.62 Example: to divide 196 by 2.5: To make 2.5 a whole number, move the decimal point 1 place to the right to give 25, So move the decimal point of 196 to the right 1 place to give 1960. Now do 1960 divided by 25 to give 78.4 When moving the decimal point in the dividend to the right, if you run out of digits before you've moved enough places, add zeros so that the decimal point moves the correct number, for example: To divide 1234.5 by 2.345: To make 2.345 a whole number the decimal point must move right 3 places to give 2345 so move decimal point of 1234.5 right 3 places, but after 1 place we have 12345 with 2 more places to move, so add 2 zeros to give 1234500 Now divide 1234500 by 2345.
Why is it important to align decimal point when adding or subtracting decimal numbers?
Because if you dont , your answer will be a whole number and that will make your answer wrong
When you add or subtract what is the rule for determining the number of significant figures in the answer?
When adding or subtracting numbers, the result should have the same number of decimal places as the least number of decimal places in the original numbers. This is because in these operations, you are limited by the least precise measurement. Significance figures don't matter in addition or subtraction, only decimal places.
