How it works ?
Step 1: Subtract Fraction checkbox to activate the operation of subtraction of proper fractions in the applet.
Step 2: Enter the numerators and denominators into the input boxes below (beige colored boxes).
Step 3: Click on the “Next Step” button (green) to go through the process of forming equivalent fractions, combining into a single fraction and adding numerators for fractions with common denominators.
Step 4: When the “<= Move Pie =>” slider appears, you can use it to shift the blue fraction pie towards or away from the red fraction pie.
Step 5: DetachPie slider to show visually the resulting fractions from.
(i) addition of proper fractions resulting in proper fractions, improper fraction or mixed numbers.
(ii) subtraction of proper fractions resulting in remaining proper fractions or negative fractions.
Step 6: The “Next Step” button changes to “Start over with New Inputs” and input boxes reappear to allow for new inputs.
