Skill: Convert percents to decimals

A percent is a rate per 100, so converting it to a decimal means expressing the same quantity in base-ten notation by dividing by 100, or moving the decimal point two places left and retaining zeros as needed (for example, $45\%=0.45$, $7\%=0.07$, and $125\%=1.25$). This connects percent, hundredths, and decimal place value for comparing quantities and solving proportional problems; the scope is exact, familiar terminating values rather than repeating decimals or more advanced generalized cases.
