2. We now study the operations of multiplication and division on fractions as well as on decimals in NCERT solutions for class 7 Maths chapter 2.
3. We have learnt how to multiply fractions. Two fractions are multiplied by multiplying their numerators and denominators seperately.
4. The product of two proper fractions is less than each of the fractions that are multiplied.
5. The product of a proper and an improper fraction is less than the improper fraction and greater than the proper fraction.
6. The product of two improper fractions is greater than the two fractions.
7. A reciprocal of a fraction is obtained by inverting it upside down.

9. While dividing a fraction by a whole number we multiply the fraction by the reciprocal of the whole number.
10. While dividing one fraction by another fraction, we multiply the first fraction by the reciprocal of the other.
11.In NCERT solutions for class 7 Maths chapter 2 We also learnt how to multiply two decimal numbers. While multiplying two decimal numbers, first multiply them as whole numbers. Count the number of digits to right of the decimal point in both the decimal numbers. Add the number of digits counted.Put the decimal point in the product by counting the digits from its right most place. The count should be the sum obtained earlier.
12. To divide a decimal number by a whole number, we first divide them as whole numbers . Then place the decimal point in the quotient as in the decimal number.
13. To divide a decimal number by 10, 100 or 1000, shift the decimal number to the left by as many places as there are zeros over 1, to get the quotient .
