Question

На хлебозавод привезли 16 машин муки.В каждой машине по 3 1/2 тонны муки.В 1 день израсходовали 25% всей муки,во 2 день 50% оставшейся муки.Сколько муки осталось

Answer 1

3 1/2=7/2
16*7/2=56(т) муки привезли всего
56*25/100=14(т) -израсходовали за 1 день
56-14=42(т)-осталось после первого дня
42*50/100=21(т) расходовали за 2 день и столько же и осталось

Answer 2

Calculation of Remaining Flour

To calculate the amount of flour that is left after two days, we need to follow the given information step by step.

1. Number of trucks: 16 2. Amount of flour in each truck: 3 1/2 tons

To find the total amount of flour delivered, we multiply the number of trucks by the amount of flour in each truck:

16 trucks * 3 1/2 tons/truck = 56 tons of flour delivered

Now, let's calculate the amount of flour used each day:

1. On the first day, 25% of the total flour was used. - Amount used: 25% * 56 tons = 14 tons

2. On the second day, 50% of the remaining flour was used. - Remaining flour after the first day: 56 tons - 14 tons = 42 tons - Amount used: 50% * 42 tons = 21 tons

To find the amount of flour that is left, we subtract the total amount used from the initial amount delivered:

56 tons - 14 tons - 21 tons = 21 tons

Therefore, there are 21 tons of flour left after two days.
