Interactive fraction.

About fractions, and the construction of the rational numbers: ℚ set.

To play with proper and improper fractions, positive and negative also.

About fractions, and the construction of the rational numbers: ℚ set.

To play with proper and improper fractions, positive and negative also.

All fractions in order from least to greatest. You can increase or decrease the fractions included in the app, increasing or decreasing the density of lines in the lower graph framework. The accuracy of the application depends on the capabilities of the device.

The application provides two representations: a circle and a straight line whose has the slope of chosen fraction

Spin the fraction: You can choose different fractions in order from low to high within the possibilities included in the grid at the bottom formed by pairs of integers.

Select equivalent fractions with the rational representation diagram (the lower grid).

Change range of fractions affordable with a "pinch zoom" on the lower grid.

In the vertical strip of the grid graph goes from 0 to 1 you can see the number of units containing the selected improper fraction: Each unit is a black square.

The program is useful to learn about fractions, coordinate geometry, rational numbers, cartesian plane, slope, and the equivalent classes of pairs of integers.
