For proper and improper fractions, we use it directly but for mixed fractions, first, we convert mixed fractions into improper fractions and then multiply.
In the multiplication of a fraction by a fraction, we simply multiply the numerator of one fraction to the numerator of another fraction and the denominator of the same fraction to the denominator of another fraction.
Multiplication of a Fraction by a Fraction Note – In fractions, the operator ‘of ’ also represents the multiplication so we use the sign of multiply in the place of the operator ‘of ’. This multiplication is used directly for proper and improper fractions but for mixed fractions, first, we convert mixed fractions into improper fractions and then multiply. In the multiplication of a fraction and a whole number, we multiply the whole number to the numerator of the fraction and the denominator remains unchanged. Multiplication of a Fraction by a Whole Number Multiplication of fractions is different from these numbers. The multiplication of these types of numbers is easy because of simple numbers. We have multiplied whole numbers, natural numbers, integers, etc. If denominators are the same, we simply subtract numerators.Įxample – Subtract 1) 1/6 from 6/7 2) 3/5 from 9/5 We subtract a fraction from another fraction with the help of LCM when denominators are not the same. The Subtraction of two fractions is the same as the Addition. If denominators are the same, we simply add numerators of both fractions.Įxample – Add 1) ¾ and 7/16 2) 8/9 and 2/9 In the Addition, we add two or more than two fractions with the help of LCM when denominators are not the same. So, we multiply 5/7 by 3 and multiply ⅔ by 7. Now, we have to make denominators of both fractions equal to 21.
Solution – Here, denominators are 7 and 3. In the comparison of two fractions, we convert them into like fractions by taking LCM of their denominators.Įxample – Which fraction is greater in 5/7 and ⅔? Comparison, Addition, and Subtraction of Fractions Note – To write equivalent fractions, we just multiply the same number to the numerator and the denominator of the fraction. There can be many equivalent fractions of a fraction.Įxample – three equivalent fractions of ⅔ = 7/4 = improper fraction Equivalent FractionsĪn Equivalent fraction of any fraction represents the same part of a whole.
