A mixture is made by combining 1.70 lb of salt and 4.15 lb of water. What is the percentage of salt (by mass) in this mixture?

Total mass of mixture = 1.70 lb + 4.15 lb = 5.85 lb
% m/m of salt = 1.70 lb salt/ 5.85 lb mixture * 100 = 29.06% m/m

(1.70 lb) / (1.70 lb + 4.15 lb) = 0.2906 = 29.1% salt by mass

If you cannot do a simple division then you're gonna fail math. I promise.
