16/20, which can be simplified if you so wish.
Ratio is a fraction. Number of total marbles is the denominator, number of red marbles is numerator. So the fraction is 35/60. This can be reduced by dividing by 5/5, so the simplest form is 7/12.
14/42. You have to add the amount of marbles and then put the probabilityof answers you're looking for. Ex: 14 white marbles 28 red marbles 14+28=42 ?/42 your looking for the probability of white marbles, so you put in the amount of white marbles on the fraction. =14/42
Use this formula - 100 * red / (blue+red+yellow).
