Question

Из цистерны отлили 0,3 находящегося в ней бензина .Затем отлили 0,6 оставшегося бензина . После этого в цистерне осталось 5,88 т.бензина . Сколько тонн бензина было в цистерне первоначально?

Answer 1

1-0,6=0,4 это 5,88т
5,88:0,4=14,7т остаток после первого отлива бензина
1-0,3=0,7 -это 14,7т
14,7:0,7=21т бензина было в цистерне первоначально

Answer 2

Initial Amount of Gasoline in the Tank

To find the initial amount of gasoline in the tank, we can use the information provided.

Let's denote the initial amount of gasoline in the tank as x.

Amount of Gasoline Taken Out Initially

The first step is to pour out 0.3 tons of gasoline from the tank.

Amount of Gasoline Remaining

After pouring out 0.3 tons of gasoline, the remaining amount is x - 0.3 tons.

Pouring Out Additional Gasoline

Next, 0.6 tons of the remaining gasoline is poured out, leaving 5.88 tons of gasoline in the tank.

Equation to Solve

We can set up the following equation to solve for the initial amount of gasoline in the tank: x - 0.3 - 0.6 = 5.88

Solving for x

By solving the equation, we can find the initial amount of gasoline in the tank.

x - 0.9 = 5.88 x = 5.88 + 0.9 x = 6.78

So, the initial amount of gasoline in the tank was 6.78 tons.

This calculation is based on the given information and the equation derived from it.
