Question

В пекарне за 3 дня израсходовали 48 мешков муки. (ежедневный рассход муки один и тот же ) На сколько дней хватит 80 мешков муки, если ежегодный рассход муки не изменится . составь задачу обратную данной и реши её . пж быстрей умоляю!!!!!!

Answer 1

1) Ежедневный расход муки - 16 мешков в день. За сколько дней израсхрдуется 80 мешков?
Решение: 80:16=5 дней;
Ответ: за 5 дней.
2) Ежедневный расход муки - 16 мешков в день. Сколько мешков муки израсхрдуется за 5 дней?
Решение: 16*5=80 мешков;
Ответ: 80 мешков израсхрдуется за 5 дней.

Answer 2

Given Information:

- In a bakery, 48 bags of flour were used in 3 days. - The daily consumption of flour is constant. - We need to determine how many days 80 bags of flour will last if the annual consumption of flour remains unchanged.

Calculation:

To find out how many days 80 bags of flour will last, we can set up a proportion using the given information.

Let's assume that x is the number of days that 80 bags of flour will last.

We can set up the proportion as follows:

48 bags of flour / 3 days = 80 bags of flour / x days

To solve for x, we can cross-multiply and then divide:

48 * x = 3 * 80

Simplifying the equation:

48x = 240

Dividing both sides by 48:

x = 240 / 48

Simplifying further:

x = 5

Therefore, 80 bags of flour will last for 5 days if the annual consumption of flour remains unchanged.

Reverse Problem:

The reverse problem would involve determining the number of bags of flour needed to last for a given number of days, assuming the daily consumption remains constant.

Let's assume that y is the number of bags of flour needed to last for a given number of days.

We can set up the proportion as follows:

48 bags of flour / 3 days = y bags of flour / z days

To solve for y, we can cross-multiply and then divide:

48 * z = 3 * y

Simplifying the equation:

48z = 3y

Dividing both sides by 3:

16z = y

Therefore, to find the number of bags of flour needed to last for a given number of days, you would multiply the number of days by 16.
