The study of fractions included mixed fractions, proper fraction and improper fraction with their addition and subtraction. We also studied equivalent fractions, comparison of fractions, ordering of fractions and representation of fractions on a number line. Our study of decimals included their addition and subtraction, their comparison and the representation of decimals on a number line. In NCERT Class 7 Maths Chapter 2 Fractions and Decimals, we will study multiplication and division of decimals and fractions. A proper fraction is a fraction that represents a part of a whole and an improper fraction is a combination of a proper fraction and a whole.

Multiplication of fractions- Two fractions are multiplied by multiplying their numerators and denominators separately. Product of two fractions are writing as-

\\\frac{Product \:of\:Numerators}{Product\:of\:Denominators},\:\:\:\:\:For \:example,\:\:\:\frac{2}{3}\times \frac{5}{7}=\frac{10}{21}

Multiplication of decimals-  Two decimal numbers are multiplied by first multiply them as whole numbers. In both decimal numbers count the number of the digits to the right of the decimal point after this add the number of digits counted and put the decimal point in the product by counting the digits from its rightmost place. The count should be the same as the sum obtained earlier.

For \:\:example,\: 0.5\times 0.7=0.35
