There are two piles of coal. The second pile is 2.5 times as much as the first pile. If 3.6 tons are taken from the second pile and put in the first pile, it will be equal, How many are the first pile and the second pile? Don't give up when answering questions
If the first pile is x tons, the second pile is 2.5x tons
x+3.6=2.5x-3.6
2.5x-x=3.6+3.6
1.5x=7.2
x=4.8
4.8 tons - the first batch
4.8 × 2.5 = 12 tons
There are two piles of coal. The second pile is 2.5 times of the first pile. If 3.6 tons are taken out of the second pile and put into the first pile, the weight of the two piles of coal will be equal
How many tons of coal are there in each pile
First pile: 1
Second pile: 2.5 times
The first pile is: (3.6 + 3.6) / (2.5-1) = 4.8 (tons)
The second pile has: 4.8 × 2.5 = 12 (tons)
A: the first pile has 4.8 tons, and the second pile has 12 tons
There are two piles of coal in the warehouse. The first pile is 60 tons, and the second pile is three twentieth more than the first pile. How many tons of coal are there in the second pile?
60 + 60x3 / 20 = 60 + 9 = 69 tons
