The salt content in the solution is 16% a) How many kg of salt is there in 45 kg

The salt content in the solution is 16% a) How many kg of salt is there in 45 kg of the solution? b) How many kg of such a solution can be prepared from 4.4 kg of salt?

Solution.
1). How many kilograms of salt are there in 45 kg of solution if the salt content in the solution is 16%?
45: 100 ∙ 16 = 7.2 (kg).
2). How many kilograms of solution can be prepared from 4.4 kg of salt if the salt content in the solution is 16%?
4.4: 16 ∙ 100 = 27.5 (kg).
Answer: 7.2 kilograms of salt is contained in 45 kg of solution; from 4.4 kg of salt, you can prepare 27.5 kg of solution.
