Question

Вес ягод в ящике равен 11 килограммов. Доля воды в нем равна 99%. На складе ягоды усохли (часть воды испарилась), доля воды стала равна 98% . Чему теперь равен вес ягод (в килограммах)?

Answer 1

Ответ:

10,(8) килограммов

Пошаговое объяснение:

Чистой воды пропорция

$99 \% = 11\\98 \% = x\\\\x = \frac{98*11}{99} = \frac{98}{9} = 10\frac{8}{9} = 10,(8)$

Answer 2

#### Calculation of the Weight of Berries To determine the weight of the berries after they have dried out, we can use the information provided. We know that initially, the weight of the berries in the box was 11 kilograms, and the water content was 99%. After the berries dried out, the water content decreased to 98%. To calculate the weight of the berries after drying, we can set up the following equation: **Initial weight of berries * (1 - Water content after drying) = Weight of berries after drying** Let's calculate the weight of the berries after drying: **Initial weight of berries = 11 kilograms** **Water content after drying = 98% = 0.98** **Weight of berries after drying = 11 * (1 - 0.98) = 11 * 0.02 = 0.22 kilograms** Therefore, the weight of the berries after drying is **0.22 kilograms**.
