To divide a decimal by a whole number, divide as you would for whole numbers; and place a decimal point in the answer so that it lines up with the decimal point in the dividend.
A good example of this is money: Three and one-fourth dollars is an amount between 3 dollars and 4 dollars. We use decimals to write this amount as $3.25. A decimal may have both a whole-number part and a fractional part. The whole-number part of a decimal are those digits to the left of the decimal point.The fractional part of a decimal is represented by the digits to the right of the decimal point. The decimal point is used to separate these parts.Let's look at some examples of this. good example of this is money: Three and one-fourth dollars is an amount between 3 dollars and 4 dollars.
