Question

На складе было 2,8 т риса. В магазин и детские сады отправили 70 процентов всего риса, причём в магазин отправили на 1,48 т риса больше, чем в детские сады. Сколько тонн риса получили детские сады?

Answer 1

70%всего риса=2,8*70/100=1,96т.
х+1,48+х=1,96
2х=1,96-1,48
2х=0,48
х=0,24
0,24т отправили в детский сад, 0,24+1,48=1,72т отправили в магазин

Answer 2

Calculation of Rice Sent to the Store and Kindergartens

To calculate the amount of rice received by the kindergartens, we need to follow the given information step by step.

1. The total amount of rice on the warehouse was 2.8 tons. 2. 70% of the total rice was sent to both the store and kindergartens. 3. The store received 1.48 tons more rice than the kindergartens.

Let's calculate the amount of rice received by the kindergartens.

Calculation Steps:

1. Calculate the total amount of rice sent to both the store and kindergartens: - 70% of 2.8 tons = 1.96 tons.

2. Calculate the amount of rice sent to the store: - Let's assume the amount of rice sent to the kindergartens is x tons. - The amount of rice sent to the store is x + 1.48 tons.

3. Set up an equation to solve for x: - x + (x + 1.48) = 1.96 - 2x + 1.48 = 1.96 - 2x = 1.96 - 1.48 - 2x = 0.48 - x = 0.48 / 2 - x = 0.24 tons

Therefore, the kindergartens received 0.24 tons of rice.

Please note that the calculations are based on the given information and assumptions made during the calculation process.
