Question

До обеда магазин продал 5/9 всех тортов после обеда половину остатка и последние 12 тортов. сколько тортов продали за день

Answer 1

Всего было тортов 1 (единица) , тогда :
1-5/9=9/9-5/9=4/9-(тортов) осталось после обеда.
4/9×1/2=4/18 (тортов)-1/2 остатка ( продали после обеда).
12тортов - это тоже 1/2 остатка (тк 1/2-это половина).
12÷1/2=12×2/1=24 (торта)- остаток после обеда.
24÷4/9=24×9/4=54 (торта )-было всего.
Проверяем:
54×5/9=30-тортов продали до обеда
54-30=24-торта осталось
24×1/2=12 -тортов продали после обеда
24-12=12-тортов - последние проданные.

Calculation of the Number of Cakes Sold

To calculate the number of cakes sold for the day, we need to follow the given information step by step.

1. Before lunchtime, the store sold 5/9 of all the cakes. 2. After lunchtime, they sold half of the remaining cakes. 3. Finally, they sold the last 12 cakes.

Let's calculate the number of cakes sold using these steps.

1. Before lunchtime, the store sold 5/9 of all the cakes. 2. After lunchtime, they sold half of the remaining cakes. 3. Finally, they sold the last 12 cakes.

To calculate the number of cakes sold before lunchtime, we need to find 5/9 of the total number of cakes. Unfortunately, the exact total number of cakes is not provided in the question. Therefore, we cannot determine the exact number of cakes sold before lunchtime.

However, we can still provide a general formula to calculate the number of cakes sold based on the given information.

Let's assume the total number of cakes is represented by the variable "x."

1. Before lunchtime, the store sold 5/9 of all the cakes, which can be calculated as (5/9) * x. 2. After lunchtime, they sold half of the remaining cakes, which can be calculated as (1/2) * (x - (5/9) * x). 3. Finally, they sold the last 12 cakes, which can be calculated as 12.

To find the total number of cakes sold for the day, we need to add up the number of cakes sold before lunchtime, after lunchtime, and the last 12 cakes:

Total number of cakes sold = (5/9) * x + (1/2) * (x - (5/9) * x) + 12

Unfortunately, without the exact total number of cakes, we cannot calculate the specific number of cakes sold for the day.
