fresh grapes lose 80% of their weight while drying. what weight of fresh grapes should you dry to get 140 grams of dried grapes

700 grammes

Step-by-step explanation:

If they lose 80% while dried, it means they have 20% of their weight after drying.

From the information in the question, we can see that the 20% here correlates with 140gramms. This means 1/5 of the weight is 140gramms.

Now let’s say total weight is x. It means 1/5 * x = 140. This means x/5 = 140.

Hence, x = 700 grammes

the answer is c. 23/3
