- [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.
