There is a total of 600 blue, yellow, and red balls in a machine.

The ratio of blue balls to the total number of balls is 1:4 600/4= 150 blue balls

The ratio of yellow balls to blue balls is 7:3. 600-150-100= 350 yellow balls

The ratio of blue balls to red balls is 3:2 if there are 150 blues balls then there are 100 red balls
