Mother bought apples and pears. The ratio of apples to pears is 4:5. I ate two apples, and the apples accounted for two-thirds of the pears. How many pears are there?
According to the problem, the ratio of apples to pears is 4∶5, that is, apples account for 4/5 of pears, and pears are determined as multiples of 1.
Among them, eating two apples changed the number of apples in the pear, and it was found that the corresponding number of apples in the multiple of 1 was (4/5-2/3), so the corresponding number was = 1 (pear).
