      2.

      3.

      4. The value of the product of two proper fractions is smaller than each of the two fractions.

      5. The value of the product of an improper fraction and proper fraction is less than improper fraction but greater than proper fraction.

      6. The value of the product of two improper fractions is more than each of the two fractions.

      7. Always convert mixed fraction into improper fraction and then do multiplication or division.

      8. If the answer is improper fraction, then convert it to mixed fraction.

      9. Reciprocal of a fraction a/b is b/a.

      10. The product of fraction and its reciprocal is 1.

      11. Dividing a whole number by a fraction:

      a ÷ b = a × (reciprocal of b)

      12. Dividing one fraction by another:

      (a/b) ÷ (c/d) = (a/b) × (d/c)

      13. While multiplying the number by 10, 100, 1000 just shift the decimal point in the quotient to the right by as many places as there are number of zeros over 1.
