Question

В первый день израсходовали 7/20 бочки горючего, во второй день на 3/20 бочки меньше, а в третий день на 1/20 бочки больше, чем в первый день. Сколько литров горючего за эти три дня, если в бочке было 180 кг. горючего?

Answer 1

1/20=180/20=9 кг
7/20=180/20*7=63 кг - в первый день
3/20=9*3=27
63-27=36 кг - во второй день
63+9=72 кг - в третий день
63+36+72=171 кг - за три дня

Answer 2

Calculating Fuel Consumption

To calculate the total fuel consumption over the three days, we can follow these steps:

1. Calculate the amount of fuel used on each day. 2. Convert the amount of fuel used from barrels to kilograms. 3. Add up the total fuel consumption over the three days.

Step 1: Calculate the Amount of Fuel Used on Each Day

- First Day: 7/20 of the barrel used - Second Day: 3/20 of the barrel less than the first day - Third Day: 1/20 of the barrel more than the first day

Step 2: Convert the Amount of Fuel Used from Barrels to Kilograms

Given that there are 180 kg of fuel in each barrel, we can calculate the amount of fuel used on each day in kilograms.

Step 3: Total Fuel Consumption over the Three Days

After converting the fuel usage to kilograms, we can then add up the total fuel consumption over the three days.

Let's proceed with the calculations.
