Calculate and enter the answers. Enter fractions in reduced, mixed number form, with a space separating the whole from the fractional part, and a slash separating the numerator and the denominator, omitting the whole or fraction part if they don't apply. E.g. "1 1/2", "3/4", or "5" without the quotes. You may use the TAB key to move to the next question. When you are done, click Submit.
