There are 150 tons of coal in pile a, pile B and pile C. after pile B borrowed 20 tons from pile a, it lent 35 tons to pile C. This means that the three piles of coal are exactly the same. How many tons of coal in pile a? How many tons of reactor B? How many tons of reactor C?
The final three piles are all 50, then a is 50 + 20 = 70, B is 50-20 + 35 = 65, C is 50-35 = 15
There are three piles a, B and C, with a total weight of 4500 tons. The weight of pile a is 1 / 8 less than that of pile B, and the weight of pile C is 2 / 7 more than that of pile A. how many tons are there in pile a, B and C?
A is 7 / 8 of B, and C is 2 / 7 more than a, so C is 9 / 7 of A
1-1/8=7/8
1+2/7=9/7
7 / 8 * 9 / 7 = 9 / 8, C is nine eighths of B
1+7/8+9/8=3
4500 / 3 = 1500 B
1500 * 7 / 8 = 1312.5a
1312.5 * 9 / 7 = 1687.5 C
A pile of apples, the first time to carry away all 2 / 5, the second time to carry away all 3 / 10. How much is left?
1-2 / 5-3 / 10
There was a pile of apples, half of which were carried away in the first time, three fourths of which were carried away in the second time, and what percentage of the total were carried away in the second time?
For the first time, half of them were taken away
For the second time, the total number is 3 / 4 × 1 / 2 = 3 / 8
