Step-by-step explanation: To write a percent as a decimal, first remember that a percent is a ratio that compares a number to 100.
So we can think of 11% as the ratio 11 to 100 or 11 divided by 100.
Dividing by 100 moves the decimal point 2 places to the left so 11 divided by 100 would move the decimal point 2 places to the left which would give us <em>.</em>11 or 0<em>.</em>11.
So 11% can be written as the decimal 0<em>.</em>11.
