A fruit stand had 36 oranges, 28 lemons, and 16 grapefruits.
What was the ratio of oranges to the total pieces of fruit?
A.
9 : 20
B.
1 : 2
C.
9 : 11
D.
9 : 7
36:(36+28+16) = 36:80 = ?
To find the ratio of oranges to the total pieces of fruit, we need to divide the number of oranges by the total number of fruit.
The total number of fruit is the sum of the number of oranges, lemons, and grapefruits: 36 + 28 + 16 = 80.
Therefore, the ratio of oranges to the total pieces of fruit is 36 : 80.
To simplify this ratio, we can divide both numbers by their greatest common divisor, which is 4.
36 ÷ 4 : 80 ÷ 4 = 9 : 20.
So, the ratio of oranges to the total pieces of fruit is 9 : 20.
Therefore, the answer is A. 9 : 20.
