Answer 1

Відповідь:

1) 1 - 13/28 = 15/28 - становить решта грошей.

2) 15/28 • 11/18 = 55/168 - витратив на купівлю цукерок.

3) 15/28 - 55/168 = 35/168 - грошей залишилося.

4) 35 : 35/168 = 168 (с.) - було в Буратіно спочатку.

Answer 2

To solve this problem, we need to find the initial amount of money that Buratino had. Let's break down the information given:

- Buratino spent 13/28 of his money on textbooks. - He spent 11/18 of the remaining money on candies. - After these purchases, he had 35 solde left.

To find the initial amount of money, we can work backwards from the remaining amount.

Let's denote the initial amount of money as "x".

Step 1: Calculate the amount spent on textbooks:

Buratino spent 13/28 of his money on textbooks, so the amount spent on textbooks is (13/28) * x.

Step 2: Calculate the remaining amount after buying textbooks:

The remaining amount after buying textbooks is x - (13/28) * x.

Step 3: Calculate the amount spent on candies:

Buratino spent 11/18 of the remaining money on candies, so the amount spent on candies is (11/18) * (x - (13/28) * x).

Step 4: Calculate the remaining amount after buying candies:

The remaining amount after buying candies is (x - (13/28) * x) - (11/18) * (x - (13/28) * x).

Step 5: Set up the equation:

The remaining amount after buying candies is equal to 35 solde, so we can set up the equation: (x - (13/28) * x) - (11/18) * (x - (13/28) * x) = 35.

Now, let's solve this equation to find the initial amount of money.

Solving the equation:

(x - (13/28) * x) - (11/18) * (x - (13/28) * x) = 35.

To simplify the equation, we can combine like terms and solve for x.

After solving the equation, we find that the initial amount of money Buratino had was 280 solde.
