The square root of 16/25 is 4/5, which is a rational number because it can be expressed in the form of p/q, where p and q are integers and q ≠ 0.
Finding the Square Root of 16/25
To find the square root of a perfect square fraction, we can take the square root of the numerator and the square root of the denominator separately. Let's learn the following methods:
- Direct calculation method
- Fraction simplification method
Square Root of 16/25 by Direct Calculation Method
The direct calculation method involves taking the square root of both the numerator and the denominator.
Step 1: Find the square root of the numerator, 16. √16 = 4
Step 2: Find the square root of the denominator, 25. √25 = 5
Step 3: Combine the results as a fraction. So, √(16/25) = 4/5
Square Root of 16/25 by Fraction Simplification Method
The fraction simplification method involves simplifying the fraction by taking the square root of both the numerator and the denominator.
Step 1: Identify the perfect squares in the fraction 16/25. - The numerator 16 is a perfect square of 4. - The denominator 25 is a perfect square of 5.
Step 2: Express the fraction as the product of its square roots. √(16/25) = √16 / √25
Step 3: Simplify the expression. √16 = 4 and √25 = 5 Therefore, √(16/25) = 4/5
Applications of the Square Root of 16/25
The square root of 16/25, which is 4/5, can be applied in various situations such as:

Common Mistakes and How to Avoid Them in the Square Root of 16/25
Students often make mistakes while finding square roots of fractions, such as ignoring the need to simplify both the numerator and the denominator. Let's look at some common mistakes in detail.
Mistake 1
Ignoring Fraction Simplification
When dealing with fractions, it's crucial to simplify both the numerator and the denominator separately before finding the square root. Not doing so can lead to incorrect results.
For example, √(36/49) should be simplified to 6/7, not 36/49.
Square Root of 16/25 Examples
Problem 1
Can you help Max find the side length of a square box if its area is 16/25 square units?
The side length of the square box is 4/5 units.
Explanation
The side length of a square is the square root of its area. Given that the area is 16/25, the side length = √(16/25) = 4/5.
Problem 2
A rectangle has an area of 16/25 square meters. If its length is 4/5 meters, what is its width?
The width of the rectangle is 1 meter.
Explanation
Area of a rectangle = length × width.
Given area = 16/25 and length = 4/5, width = area/length = (16/25) / (4/5) = 1.
Problem 3
Calculate (16/25)^(1/2) × 10.
8
Explanation
First, find the square root of 16/25, which is 4/5. Then, multiply by 10: (4/5) × 10 = 8.
Problem 4
What will be the square root of (9/16) + (16/25)?
The square root is 49/20 or 2.45
Explanation
First, find the sum of (9/16) + (16/25) = (225/400) + (256/400) = 481/400. The square root of 481/400 is approximately 2.45.
Problem 5
Find the hypotenuse of a right triangle if one leg is 3/5 units and the other leg is 4/5 units.
The hypotenuse is 1 unit.
Explanation
Using the Pythagorean theorem: hypotenuse² = (3/5)² + (4/5)² = 9/25 + 16/25 = 25/25 = 1. Therefore, the hypotenuse = √1 = 1 unit.
