A fraction is a perfect square if the square root of both the numerator and the denominator are perfect squares.
Here's how to determine if a fraction is a perfect square:
- Check the Numerator: Determine if the numerator is a perfect square. This means finding out if the square root of the numerator is an integer.
- Check the Denominator: Determine if the denominator is a perfect square. This means finding out if the square root of the denominator is an integer.
- Evaluate: If both the numerator and the denominator are perfect squares, then the entire fraction is a perfect square.
Example:
Consider the fraction 9/16.
- The square root of the numerator (9) is 3, which is an integer.
- The square root of the denominator (16) is 4, which is an integer.
Since both the square root of 9 and the square root of 16 are integers, 9/16 is a perfect square, as mentioned in the reference (Decimal and Fraction Perfect Squares - YouTube).
