While multiplying a whole number by a mixed fraction, change the mixed fraction into an improper fraction.

To multiply two proper fractions, multiply their numerators and denominators

Note:   When two proper fractions are multiplied, the product is less than each of the individual fractions. When two improper fractions are multiplied, the product is greater than each of the individual fractions.

Division of Fractions

To obtain the reciprocal of a fraction, interchange the numerator with the denominator.

To divide a whole number by a fraction, take the reciprocal of the fraction and then multiply it by the whole number

To divide a fraction by a whole number, multiply the fraction by the reciprocal of the whole number.

To divide a fraction by a fraction, multiply the first fraction by the reciprocal of the second fraction.

To multiply a whole number by a decimal number, follow these steps:

1. Ignore the decimals and multiply the two numbers.
2. Count the numbers of digits to the right of decimal point in the original decimal number.
