Write as a fraction: 4.5%

4.5% = (4 1/2)% = (9/2)%.

(9/2)%/100% = 9/2 * 1/100 = 9/200.

Check: 9/200 * 100% - 900%/200 = 4.5%.

To write 4.5% as a fraction, follow these steps:

Step 1: Convert the percentage to a decimal by dividing it by 100.
4.5% ÷ 100 = 0.045

Step 2: Write the decimal as a fraction by placing it over 1 and multiplying both the numerator and denominator by 100 to eliminate the decimal.
0.045 = 0.045/1

Step 3: Simplify the fraction if possible. In this case, both the numerator and denominator are divisible by 5.
0.045/1 = 45/100

Step 4: Further simplify the fraction by dividing both the numerator and denominator by their greatest common divisor (GCD). In this case, the GCD is 5.
45 ÷ 5 / 100 ÷ 5 = 9/20

Therefore, 4.5% is equivalent to the fraction 9/20.
