Practice Cancellation in Math
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
Cancellation is the process of removing a common factor from the numerator and denominator of a fraction, or from both sides of an equation, to simplify. It works because dividing both parts by the same nonzero number leaves an equivalent but simpler form.
because we can cancel the common factor 2 from top and bottom.
