The ratio for the problem above is one to four. A ratio is a relationship between number which describes how many times the second number contains the first number. The problem above gave two metric unit of length which are the centimeter and meter and the ratio between those two is one to a hundred. Therefore, we have a comparison between two amounts which are 75 and 300 and we can conclude a ratio of one to four.
Since Mitchell will be making 50% more coffee than usual, we need to multiply 100 grams of coffee by 1.5, giving us 150 grams of coffee. But because we need to use 20% more coffee grounds, multiply 150 by .2 and add that amount to 150. So the answer is 180 grams of coffee.
