In Question 2 above, if 1 part of a red pigment requires 75 mL of base, how much red pigment should we mix with 1800 mL of base?


The table of the given information is as follows:


Parts of Red Pigment



1



x



Parts of base



75ml



1800ml



The parts of the red pigment and parts of base are in direct proportion,


Therefore,


1/75 = x/1800


x = 24


Thus, 24 parts of the red pigment mixed with 1800 ml of base.
