Mistakes You Can Avoid

When in a hurry, it’s easy to mess up even the most straightforward calculations. Below, you’ll find out the most common mistakes.

1. Moving the decimal in the wrong direction
Be careful not to move the decimal the wrong direction when calculating from percentage to decimal.

Example:
65% → 0.65, not 6.5.

2. Forgetting to write 0 for small percentages
When working with small percentages, don’t forget to write 0 before the decimal point.

Example:
5% → 0.05, as opposed to .05 or 0.5.
Using 0.5 instead of 0.05 makes a huge difference.

3. Neglecting the changing the decimal point in cases of percentages involving decimals.
It’s important to keep in mind that if there’s a decimal found in the percentage value, you need to move it two places left from where it’s located.

Example:
0.75% = 0.0075 instead of 0.075.

4. Mistaking percentages more than 100
If a percentage figure exceeds 100% its decimal value is considered to be greater than 1.

Example:
150% = 1.5 instead of 0.15.

5. Forgetting the context
When a decimal is used alone, its value and meaning don’t always indicate the entire picture. E.g., one can have numbers 0.05, which could mean 5% or 0.05 of the total amount.
