Don't forget, per cent means per hundred, e.g. 10% = 10100. Suppose you were asked to find 10% of 50, how would you do it? This is how you would do it: 10100 × 50 = (10 × 50) ÷ 100 = 5. It's as simple as that!

5.5% of 100 = 5.5100 × 100 = (5.5 × 100) ÷ 100 = 5.5. You shouldn't have had to calculate anything in this question because X% of 100 = X for all values of X
3.
What is 25% of 75?
0.1875
1.875
187.5
18.75
25% of 75 = 25100 × 75 = (25 × 75) ÷ 100 = 18.75. DON'T forget: when you divide by 100, move the decimal point two places to the left
