How to Calculate Square Roots of Fractions

The square root of a fraction is calculated by taking the square root of the numerator and the denominator separately. The formula is:

Formula

√(a/b) = √a / √b

Where:

  • a is the numerator
  • b is the denominator

After calculating the square roots of the numerator and denominator, you may need to simplify the resulting fraction.

Note

The square root of a fraction is only defined when both the numerator and denominator are non-negative numbers.

Examples of Square Roots of Fractions

Example 1: Simple Fraction

Calculate √(4/9):

  1. √4 = 2
  2. √9 = 3
  3. √(4/9) = 2/3

The square root of 4/9 is 2/3.

Example 2: Improper Fraction

Calculate √(16/25):

  1. √16 = 4
  2. √25 = 5
  3. √(16/25) = 4/5

The square root of 16/25 is 4/5.

Example 3: Mixed Number

Calculate √(3/4):

  1. Convert 3/4 to an improper fraction: 3/4
  2. √3 ≈ 1.732
  3. √4 = 2
  4. √(3/4) ≈ 1.732/2 ≈ 0.866

The square root of 3/4 is approximately 0.866.
