Apple is 1 / 5 more than pear. How many times is the weight of apple? How many times is the weight of pear?
The weight of apple is 1.2 times that of pear, and the weight of pear is 5 / 6 of that of apple
The weight of a pear is 3 / 4 more than that of an apple, which is regarded as "1". The weight of a pear is equivalent to several parts of the weight of an apple
The weight of a pear is 3 / 4 more than that of an apple. The weight of a pear is 7 / 4 of that of an apple
In a pile of apples, a and B ate half of the total, a and C ate one-third of the total, a and d ate a quarter of the total, and how much did a eat
1/24
Solution 1: I don't know if you have studied the multivariate equation. Suppose that a, B, C and d eat x, y, Z and W apples (the fraction of the total number), then x + y = 1 / 2, x + Z = 1 / 3, x + W = 1 / 4. In addition, there is a hidden condition, that is, x + y + Z + W = 1. Then a 1 / 24, B 11 / 24, C 7 / 24, D 5 / 24 can be solved
Solution 2: you can also see that a + B = 1 / 2, the sum of four people is 1 / 2, so c + D = 1 / 2 (formula 1), while a + C = 1 / 3, a + D = 1 / 4, subtracting the two to get C-D = 1 / 12 (formula 2). Add Formula 1 and formula 2 to get C = 7 / 24, and then get the others
A pile of apples were put into four boxes, 4 / 1 put a 5 / 1 put B put C apple is four times the quantity difference between a and B, how many percent of the total number of Ding Li put apple
The number of C apple is 4 times of the difference between a and B, then C apple is (1 / 4-1 / 5) × 4 = 1 / 5 of the total
Therefore, 1-1 / 4-1 / 5-1 / 5 of the total number of apples in dinglifang is 7 / 20
