The picture will show that 7 of the 9 cookies are square cookies.

All fractions must be less than or equal to one. The denominator must be 20 or less.

The <EXPLAIN> checkbox checked will show how the fraction of square cookies is calculated. Uncheck <EXPLAIN> to hide the explanation, allowing the teacher or learner to demonstrate how to write the fractions.

With <SHOW INPUT> unchecked, the numerator and denominator input boxes will act the same as password input boxes so learners will not see the numbers you input.
