Question

Утром на базе было 19 тонн муки . До обеда с базы выдали в 3,2 раза больше муки , чем после обеда . К вечеру на базе осталось 4,3 тонн муки . Сколько тонн муки выдали с базы до обеда ?

Answer 1

х (т) - муки - после обеда

3,2х (т) - муки - выдали до обеда.

1) 19-4,3=14,7 (т) - муки выдали всего

2) х+3,2х=14,7

   4.2х=14,7

    х-14,7:4,2

    х=3,5 (т) - выдали после обеда

    3,5*3,2=11,2 (т) - выдали до обеда.

Answer 2

Calculation of Flour Distributed Before Lunch

To calculate the amount of flour distributed from the base before lunch, we need to subtract the amount of flour left at the end of the day from the total amount of flour at the beginning of the day.

Given the following information: - Total amount of flour in the morning: 19 tons - Amount of flour left in the evening: 4.3 tons

To find the amount of flour distributed before lunch, we can subtract the amount of flour left in the evening from the total amount of flour in the morning:

Amount of flour distributed before lunch = Total amount of flour in the morning - Amount of flour left in the evening

Amount of flour distributed before lunch = 19 tons - 4.3 tons

Now, let's calculate the result:

Amount of flour distributed before lunch = 14.7 tons

Therefore, 14.7 tons of flour were distributed from the base before lunch.
