Explanation:
To convert the fraction 20/50 into a percent, we need to change the denominator of the fraction to 100. Now, we ask ourselves, what do we multiply 50 by to get 100? The answer is 2. Hence, we do the same to the numerator: 20 * 2 = 40. Thus, when 20/50 is converted to a fraction over 100, it becomes 40/100, or simply 40%.
