Problem Analysis

We are given that 21 kg of fresh raspberries results in 3 kg of dried raspberries. We need to find out how much fresh raspberries were used to obtain 5 kg of dried raspberries.

Solution

Let's assume that x kg of fresh raspberries were used to obtain 5 kg of dried raspberries.

We can set up a proportion to solve for x: 21 kg fresh raspberries / 3 kg dried raspberries = x kg fresh raspberries / 5 kg dried raspberries

To solve for x, we can cross-multiply and then divide: 21 kg * 5 kg dried raspberries = 3 kg * x kg fresh raspberries

Simplifying the equation: 105 kg dried raspberries = 3x kg fresh raspberries

Dividing both sides by 3: 35 kg dried raspberries = x kg fresh raspberries

Therefore, 35 kg of fresh raspberries were used to obtain 5 kg of dried raspberries.

Answer

If 5 kg of dried raspberries were obtained, then 35 kg of fresh raspberries were used to obtain that amount.
