How Do You Multiply Fractions in Class 5 Maths?

Published in Fraction Multiplication 2 mins read

Multiplying fractions is straightforward! You simply multiply the numerators (top numbers) together and then multiply the denominators (bottom numbers) together.

Steps to Multiply Fractions:

  1. Multiply the numerators: This gives you the numerator of your answer.
  2. Multiply the denominators: This gives you the denominator of your answer.
  3. Simplify (if possible): Reduce the resulting fraction to its simplest form by finding the greatest common divisor (GCD) of the numerator and denominator and dividing both by it.

Examples:

  • Example 1: ⅔ × ½

    Following the steps:

    1. Numerators: 2 × 1 = 2
    2. Denominators: 3 × 2 = 6
    3. Resulting fraction: 2/6
    4. Simplification: 2/6 simplifies to ⅓ (dividing both numerator and denominator by 2).

  • Example 2: ⅘ × ⅞

    1. Numerators: 4 × 7 = 28
    2. Denominators: 5 × 8 = 40
    3. Resulting fraction: 28/40
    4. Simplification: 28/40 simplifies to 7/10 (dividing both by 4).

  • Example 3: ¼ × ⅖ × ⅛

    1. Numerators: 1 × 2 × 1 = 2
    2. Denominators: 4 × 5 × 8 = 160
    3. Resulting fraction: 2/160
    4. Simplification: 2/160 simplifies to 1/80 (dividing both by 2).

  • Example 4: 5 × ½

    Remember, a whole number can be written as a fraction with a denominator of 1. So, 5 can be written as 5/1.

    1. Numerators: 5 × 1 = 5
    2. Denominators: 1 × 2 = 2
    3. Resulting fraction: 5/2
    4. This can also be written as a mixed number: 2 ½

Multiplying Fractions with Whole Numbers:

To multiply a fraction by a whole number, simply write the whole number as a fraction (over 1) and follow the steps above.

These examples demonstrate the basic process of multiplying fractions, a crucial skill for Class 5 math. Remember to always simplify your answer to its lowest terms!
