Guide
The bars are the same length and sit one under the other. If the shading on two bars ends in exactly the same place, the two fractions are equal.
Use the + and − buttons to change the number of parts. The coloured line shows where the amount ends. You can only show that amount with these parts when the line falls on a border between two parts.
If you split every part into 2 equal parts, the number of parts (the denominator) doubles and so does the number of shaded parts (the numerator): 13 = 26.
To simplify a fraction you do the opposite: make the parts bigger so the numerator and denominator get smaller, while the amount stays the same.
