Fractions101

This is a visual representation of fractions as ratios of whole positive numbers and their addition and subtraction.

Two proper fractions are shown as top and bottom bars allowing their relative magnitudes to be compared.  The fractional notation is shown as well as the equivalent decimal value.

Button B allows changes to be made to the denominator and numerator of the two fractions in sequence (Den1, Num1, Den2, Num2) with the last in the sequence (Math) allowing them to be added or subtracted.

The denominator and numerator of each fraction can be changed by pressing Buttons C&D
