How to convert percentages to numbers: 1) Remove the percent sign % 2) Shift the decimal separator two places to the left

- Percent, p%, means 'out of one hundred' and is read p 'percent';
- 45% means 45 out of one hundred and is read 45 percent.
- p% can be written as a fraction:
^{p}/_{100}, where / is the fraction bar, p is the numerator and 100 is the denominator; - 45% =
^{45}/_{100}, where 45 is the numerator and 100 is the denominator of the fraction. - p% can be written as a division: p ÷ 100, where p is divided by 100;
- 45% = 45 ÷ 100, where 45 is divided by 100.

- Divide the p number by 100: p% = p ÷ 100;
- 45% = 45 ÷ 100 = 0.45.

- We can summarize in two simple steps the operation of converting (writing) a percent value to a decimal, integer or whole number:
- 1) Remove the percent sign % ...
- 2) Move the decimal point two places to the left.

- 45% = 0.45; 145% = 1.45; -11% = -0.11; -229% = -2.29; 400% = 4; -700% = -7.
- 45.836% = 0.45836 ≈ 0.46 (rounded up to the nearest tenth, two decimal places);
- 145.26% = 1.4526 ≈ 1.45 (a maximum of two decimal places);
- -11.7% = -0.117 ≈ -0.12; -229.555% = -2.29555 ≈ -2.3.
