Let 320 be 100%.
1. Let’s find how many grams of alloy are in 1%, dividing the mass of the entire alloy by percent.
320/100 = 3.2 (g) falls on 1%.
2. Let’s find the percentage of tin in this alloy by dividing the entire weight of the tin by the number of grams per 1%.
112 / 3.2 = 35% of the tin is in glory.
Answer: 35%.
