Equivalent Fractions

Experiment with manipulating the blue sliders to change the left hand fraction. Use the green sliders to perform an operation on the numerator and/or the denominator. Use the verify slider to test equivalence.
What happens if you multiply or divide the numerator and denominator by the same value? What happens if you add or subtract the same value to the numerator and the denominator? Can you explain why?
