In this problem substitution works well.

lets make it 100 pounds.

this means that there is a total of 90 pounds material and 10 pounds package.

if the weight is half, then we have 50 pounds-10 pounds of packaging equals 40 pounds.

40 pounds over 90 pounds equals 4/9

Thank you! It's a good method!
I solved it using equations and it took me long...
