Percentage of P = (Parts of P / Total parts) * 100
Percentage of Q = (Parts of Q / Total parts) * 100
So the total parts are 18 + 12 = 30.
Percentage of P = (18 / 30) * 100 = 60%
Percentage of Q = (12 / 30) * 100 = 40%
So, in the mixture, chemical P makes up 60% of the mixture, and chemical Q makes up 40% of the mixture.
HOPE IT HELPS :D
