Aschool’s yearbook committee had many meetings last month the line plot summarizes how long each meeting lasted

On the graph, it shows that the shortest meeting has lasted for 1/4 of an hour. An hour has 60 mins, you know it the shortest will be 15 minutes.

If its for any other number that you do not know, you can list as a proportion:

1/4 = x/60 (1 and x are on the top of the fractions)

Cross multiply: 1 * 60 = 60

Then divide by the number on the opposite corner of x: 60/4

x = 15

it would be:

c.parallelogram.
