Answer:

C- mean: 9/20, median: 2/5, mode: 3/4

Step-by-step explanation:

I used process of elimination so it only took a minute, rather than adding all of them up and finding a common denominator.  

3/4 shows up twice while the rest show up once, its obviously the mode.

if you put them in order:

1/10 , 1/4 , 2/5, 3/4 , 3/4

you have 2/5 in the middle.

(And if you want to do the whole thing, an easier way to find the mean is changing them to decimals (.1, .25, .4, .75, .75) and changing them back to fractions once you have the answer is an easier way of doing it.
