Answer 3

According to the given information, Malvina ate 7/8 of the raspberries and gave some to Papa Carlo and Buratino. Buratino then ate 4/5 of what Malvina gave him. We need to find out how many raspberries there were in total, given that Buratino ate 280 grams.

Let's solve this step by step:

1. Let's assume the total amount of raspberries is represented by the variable "x". 2. Malvina ate 7/8 of the raspberries, so she had (1 - 7/8) * x = 1/8 * x left. 3. Malvina gave this remaining amount to Papa Carlo and Buratino. 4. Buratino ate 4/5 of what Malvina gave him, so he ate (4/5) * (1/8) * x = 4/40 * x = 1/10 * x. 5. We know that Buratino ate 280 grams, so we can set up the equation: 1/10 * x = 280. 6. To find the value of x, we can multiply both sides of the equation by 10: x = 280 * 10 = 2800.

Therefore, there were 2800 grams of raspberries in total.

Calculation Steps:

1. Total amount of raspberries: x 2. Amount Malvina had left: (1 - 7/8) * x = 1/8 * x 3. Amount Buratino ate: (4/5) * (1/8) * x = 1/10 * x 4. Equation: 1/10 * x = 280 5. Solve for x: x = 280 * 10 = 2800

So, there were 2800 grams of raspberries in total.
