a dot used to separate the whole part of a mixed number from its fractional part: for example, in the mixed number 32.89, the whole part is 32 whole units, the fractional part is 89 one-hundredths, and the dot that allows for the expression 32.89 is the decimal point: If you want to multiply 14.675 by 10, just move the decimal point one place to the right to get 146.75, the correct answer.
