Moved from a technical forum, so homework template missing.

I 'am stuck at , what fraction of the shoes were size 4 I know the frequency is missing. The frequencies are 8,9,9,3,1.
My thinking you how to add the frequencies and put 4 over it. Explain to me if I'm wrong.
Thanks in advance

How many shoes were sold in total (the "frequency" thing seems weird to me for some reason) and how many were sold of size 4?

Count again. There are no repeated frequencies.

Why would you use 4?
The frequency (or relative frequency) for a given show size is ##\frac{\text{number of pairs of shoes sold of a given size}}{\text{total number of pairs of shoes sold of all sizes}}##

Check the third frequency, does not seem to agree with the tally.
