The weight of the raisins is 25% of the weight of the grapes taken for drying. How many raisins are obtained from 48 kg of grapes?
Let’s make a proportion, in which we denote the weight of the grapes as 100%, and the weight of the raisins as x kg.
In this case, we get equality in which the weight of the grapes is related to 100% in the same way as the unknown weight of raisins is related to 25%.
We get:
48/100% = x / 25%.
We multiply the extreme terms of the proportion among ourselves.
100 * x = 48 * 25.
100 * x = 1200.
x = 1200/100 = 12 kg of raisins.
Answer:
From 48 kg of grapes, 12 kg of raisins will be obtained.
Second way.
We multiply the weight of the grapes by the percentage.
48 * (25% / 100%) = 48 * 0.25 = 48 * 1/4 = 48/4 = 12 kg.
