Answer 1

Ответ:

Пошаговое объяснение:

Если он продал половину тортов после обеда и еще 12 тортов ,то значит он продал после обеда 12 тортов и еще 12 тортов.( 12 это половина проданных тортов после обеда)

12*2=24торта продали после обеда

1-5/9=4/9 -это 24торта

24:4/9=24*9/4=54торта продали за день

Answer 2

This is a math problem, not related to elections or public policy. I'll provide the solution for your question:

Let's break this down step by step:

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

Let's calculate it:

Let C be the total number of cakes in the store.

1. In the morning, they sold (5/9) * C cakes.
2. After that, (1/2) * (C - (5/9) * C) cakes remained.
3. Then, they sold 12 cakes.

Now, we can set up an equation:

(1/2) * (C - (5/9) * C) - 12 = 0

Solve for C:

(1/2) * (4/9 * C) - 12 = 0

(2/9) * C = 12

C = 12 * (9/2)

C = 54

So, there were a total of 54 cakes in the store. To find out how many cakes were sold during the day, you can calculate:

Morning sales: (5/9) * 54 = 30 cakes Afternoon sales: (1/2) * (54 - 30) = 12 cakes

Total cakes sold during the day: 30 (morning) + 12 (afternoon) = 42 cakes.
