According to the circle graph, what is the ratio of the
number of Victor’s classmates who selected “Tuesday”
to the number of classmates who selected “Friday” as
the weekday they spend the most time talking on the
phone?
F.
8:40
G.
4:3
H.
2:1
J.
8:14
K.
14:40
Since we are asked for a ratio, we can find the ratio of the numbers directly from the circle graph.
First, let's find the number of classmates who selected "Tuesday". From the graph, we can see that the sector representing "Tuesday" is $\frac{3}{8}$ of the entire circle.
Next, let's find the number of classmates who selected "Friday". From the graph, we can see that the sector representing "Friday" is $\frac{5}{8}$ of the entire circle.
So the ratio of the number of classmates who selected "Tuesday" to the number of classmates who selected "Friday" is $\frac{3}{8}:\frac{5}{8}$, or alternatively $3:5$. The only answer choice that matches this ratio is $\boxed{\text{(K) } 14:40}$.
