A pile of coal, 1 / 40 of a day, 5 days, a total of a few parts of this pile of coal It's 5 days, not 1.5 days

A pile of coal, 1 / 40 of a day, 5 days, a total of a few parts of this pile of coal It's 5 days, not 1.5 days

1 / 40x5 = 1 / 8

A pile of coal weighs 1 and 1 / 4. It will be burned in 5 days. How many tons will it burn every day? How many parts will it burn every day?

Daily coal burning: 1 / 4 △ 5 = 1 / 4 ton
The total amount burned per day: 1 △ 5 = 1 / 5

A pile of coal weighs 2 tons and can be burned for 15 days. How many tons can be burned every day on average, and how many parts of this pile of coal can be burned in 4 days?
What's the formula

Two fifths of a ton
four-fifteenths

A pile of coal weighs 10 and 1 / 4 tons. It will be burned in 41 days. How many tons will it burn every day? How many parts will it burn every day?

41/4 ÷41 = 1/4
1 / 4 ton / day, 1 / 41 ton / day
