Table data — Basic example

- [Instructor] Angel's ice cream shop sells ice cream by the scoop and by the pint. The table above shows the purchases made by his customers last weekend. Of the customers who bought scoops, what fraction also bought pints? So pause this video and see if you can figure this out on your own. All right, now let's look at this. So "of the customers who bought scoops." So I can do that as the denominator of a fraction. So customers, customers buying scoops. They are saying, "what fraction also bought pints?" So bought, bought pints. So we're looking at the customers that bought the scoops. So bought scoops is right over here. And we know that there's a total of 310 that bought scoops. So this is going to be equal to 310 as our denominator and then of them, which, how many bought pints? Well, we could see that right over here, 27 bought pints. So 27 over 310, which is this choice right over here. And we're done.
