So I'm not gonna explain it because its just like the last. For vanilla you would do 2/4*100/1 and you'll get, 200/4 and 200 divided by 4 is 50 so that's your 1st answer
For Strawberry it's 3/4*100/1 and that equals 300/4 and 300 divide by 4 is 75 so that's your 2nd answer.
For chocolate its 4/4/100/1 and that is equal to 400/4 and 400 divided by 4 is 100 so 100 is your 3rd answer.
