Question

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

To calculate the amount of flour distributed from the base before lunch, we need to follow the given information:

- In the morning, there were 19 tons of flour at the base. - Before lunch, they distributed 3.2 times more flour than after lunch. - By the evening, there were 4.3 tons of flour left at the base.

Let's calculate the amount of flour distributed before lunch:

1. Calculate the amount of flour left at the base after lunch: - Flour left at the base = Flour in the morning - Flour distributed after lunch - Flour left at the base = 19 tons - 4.3 tons = 14.7 tons

2. Calculate the amount of flour distributed before lunch: - Flour distributed before lunch = Flour in the morning - Flour left at the base after lunch - Flour distributed before lunch = 19 tons - 14.7 tons = 4.3 tons

Therefore, 4.3 tons of flour were distributed from the base before lunch.
