3/4
提示Find the highest common factor of both numbers and cancel it in one go, or cancel in stages.
为什么36 and 48 share a highest common factor of 12, so dividing both by 12 gives 3/4. Cancelling in stages (÷2, ÷2, ÷3) reaches the same place — keep going until top and bottom share no factor except 1.
下次复习日期相同——「太简单」会让之后的间隔拉得更快
