Question

муж выпивает бочку воды за 14 дней а вместе с женой за 10 дней за Сколько же выпивает бочку воды жена

Answer 1

Ответ:

Пошаговое объяснение:

пусть обьем бочки воды =1

х количество воды выпивает

муж за один день

у колич. воды выпивает жена

14× х=14х=1

(х+у)×10=1 муж с женой

х=1/14 ,х+у=1/10 ,у=1/10- х=1/10 - 1/14=

= 2/70=1/35 обьем =1 разделим на

у=1/35 , 1÷1/35=35 дней

за 35 дней выпивает бочку жена

Answer 2

Calculation of Water Consumption

To calculate how much water the wife drinks, we need to determine the amount of water the husband drinks in one day.

According to the information provided, the husband drinks a barrel of water in 14 days, while the husband and wife together drink a barrel of water in 10 days.

Let's assume that the volume of the barrel is denoted by B.

Therefore, the husband drinks B/14 of water per day, and the husband and wife together drink B/10 of water per day.

To find out how much water the wife drinks, we need to subtract the husband's daily consumption from the total daily consumption of the husband and wife.

The wife's daily consumption can be calculated as follows:

B/10 - B/14

To simplify this expression, we need to find the least common multiple (LCM) of 10 and 14, which is 70.

Now we can calculate the wife's daily consumption:

B/10 - B/14 = (7B - 5B)/70 = 2B/70 = B/35

Therefore, the wife drinks 1/35 of the barrel of water per day.

Please note that the specific volume of the barrel of water was not provided, so the answer is given in terms of the fraction of the barrel consumed by the wife per day.
