Explanation

Converting a percentage to a fraction is a task that can be done easily. You can follow the steps mentioned below to find the answer.

Step 1: Firstly, convert the percentage to a decimal by dividing by 100. Here, 0.4% becomes 0.4/100 or 0.004.

Step 2: Convert the decimal to a fraction by placing 0.004 over 1. Then, 0.004 becomes 0.004/1.

Step 3: To remove the decimal from the fraction, multiply both the numerator and denominator by 1000 (because there are 3 decimal places). 0.004/1 × 1000/1000 = 4/1000

Step 4: Simplify the fraction by finding the GCD of 4 and 1000, which is 4. Divide both the numerator and the denominator by 4. 4/1000 = 1/250
