Mixed Numbers to Fractions uses circle models to demonstrate how a number in mixed form can be renamed in fraction form.
The illustration below was made by Mixed to Fraction with Circles Designer. It shows the mixed number . You are to write in fraction form, with only a numerator and denominator.
In this example, you will notice that each of the two whole circles has 5 colored pieces and the part circle has 2 colored pieces, giving 12 colored pieces in all for a numerator of 12. The denominator is 5 because each circle has 5 equal parts, giving a fraction of
Some textbooks call a fraction such as this improper, where the numerator is equal to or larger than the denominator. There is nothing improper with the fraction . This is better known as the fraction form or the form of the number, providing b is not equal to zero.
Multiply the whole number 2 by the denominator 5 and then add the numerator 2 for the numerator 12 in the fraction form.
Another way to write the example is to think of each whole number as . So in the above example you would have:
