Cancelling   You can click and drag the top slices of cake. Drag one quarter of the cake on to the right hand plate. Hint: Please make sure you get the cake on the plate! One quarter is the same as two eighths. Please note: One quarter is "equivalent" to two eighths. Equivalent means that the fractions have equal value. Writing a fraction with a smaller denominator is called "cancelling". Example: Cancel twelve over eighteen. Please note: Six is the highest common factor of twelve and eighteen. Try one! What is the highest common factor of ten and fifteen? Answer:   Comment: Use your answer to cancel ten over fifteen.
