Though it may be useful in a classroom to introduce reducing with this website, I recommend a good amount of paper and pencil work to enhance retention and comprehension. |

| SHORT DIVISION | |

When you you click the fraction button, a fraction to reduce is displayed. The common divisors are displayed to the right of the division signs. To select a pair of Greatest Common Divisors (GCD), press the up/dn arrows until the GCD's you want to select are displayed. |
You can use the short division application to divide the given numerator and denominator by a single digit GCD and find the reduced numerator and denominator. |
| After you select a pair of GCD's, divide and enter your new numerator and denominator in the textboxes to the right of the equal signs. Then, click the question button to see if your answers are correct. Choose a small fraction and below you can explore solving the fraction mechanically. | |
