1. Know what a percentage is. A percentage is a way to express a number as a part of a whole. To calculate a percentage, we look at the whole as equal to 100%. For example, say you have 10 apples (=100%).If you eat 2 apples, then you have eaten 2/10 Ã 100% = 20% of your apples and you are left with 80% of your original apples.. Know what a percentage is. A percentage is a way to express a number as a part of a whole. To calculate a percentage, we look at the whole as equal to 100%. For example, say you have 10 apples (=100%).
To calculate the percentage increase: First: work out the difference (increase) between the two numbers you are comparing. Increase = New Number-Original Number. Then: divide the increase by the original number and multiply the answer by 100.% increase = Increase Ã· Original Number Ã 100.If your answer is a negative number then this is a percentage decrease.ometimes it is easier to show percentage decrease as a negative number â to do this follow the formula above to calculate percentage increase â your answer will be a negative number if there was a decrease. In Dylanâs case the decrease works out at -15.5. -10.5 Ã· 45.5 = -0.23. -0.23 Ã 100 = -23%.
