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

The weight one can dry to get 140 grams is 700 grams

Step-by-step explanation:

Fresh grapes looses 80 percent of it weight while drying . To get 140 grams of dried grape we need to know the weight of the fresh grape.

Let the fresh grape weight = y grams

80% of the fresh grape weight will be =  80/100 × y grams

The weight of fresh grape you should dry to get 140 grams = Fresh grape weight - 80% of the fresh grape weight

140 = y - 80/100 × y

140 = y - 0.8 y

140 = 0.2y

divide both sides by 0.2

y = 140/0.2

y = 700 grams
