After you have solved a given task, you need to enter the result into the three input boxes. In the left box you enter the integer part of the fraction, in the upper box the numerator and in the lower box the denominator. If the option Mixed number in the Answer section is unchecked, the left box for the integer part of the fraction is hidden. Then you use only the numerator box and the denominator box for your input.
Després que hàgiu calculat la solució cal que escriviu el resultat en els espais preparats. En el superior heu d' escriure el numerador i en el inferior el denominador.
