# It is known that 320 g of one solution contains 112 g of salt, and 440 g of another solution contains 176 g

**It is known that 320 g of one solution contains 112 g of salt, and 440 g of another solution contains 176 g of salt. Which solution, first or second, has a higher percentage of salt.**

1. Determine the percentage of salt in the first solution. We take this percentage for a and make up the proportion:

320 g – 100%, 112 g – a%;

320: 112 = 100: a;

a = (112 x 100): 320;

a = 35%;

2. Determine the percentage of salt in the second solution. We take this percentage for a and make up the proportion:

440 g – 100%, 176 g – a%;

440: 176 = 100: a;

a = (176 x 100): 440;

a = 40%.

Answer: the salt concentration in the first solution is 35%, and the salt concentration in the second solution is 40%, which means that the percentage of salt is higher in the second solution.
