Kyle has 125 marbles. Fifty of these marbles are red and the rest are other colors. What is the ratio of the number of red marbles to the total number of marbles expressed in simplest terms?
A. 2 to 3
B. 5:2
C. 3/2
D. 2/5
It is asking in "simplest terms" so you would have to divide the number of marbles Kyle has by the 50 red marbles. 125 divide by 50 is 2.5 which equals to 2/5.
