Calculation of Percentage: Let’s solve the problem “What is 30% of 80?” Now, we can write: x = 30/100 * 80. The answer is 24. Let’s start with the number 120. First, we create a quick chart as follows: 120 = 100% 12 = 10% 1.2 = 1% 60 = 50% 6 = 5% Now, we can solve the problems using this base numbers. Example 6% of 120 = 5% + 1% = 6 + 1.2 =7.2 One other type of calcula...
