Common Mistakes
MISTAKE: Thinking 1% means 1. | CORRECTION: 1% is 1/100 or 0.01, not the number 1 itself. It's a fraction or a decimal part of a whole.
MISTAKE: Confusing 1% with 100%. | CORRECTION: 1% is a very small part (1 out of 100), while 100% means the entire thing or the whole quantity.
MISTAKE: Forgetting to divide by 100 when calculating. | CORRECTION: Always remember that 'percent' literally means 'per hundred', so you must divide the number by 100 (or multiply by 0.01) to find its percentage value.
