Convert the mixed number 2 1/4 into an improper fraction: 9/4.
Then multiply this 9/4 by 3: 27/4, or 6 3/4.
Ok to solve this just write it out how it sounds, like so.
3x/4

-16

We can figure out how many numbers there are from 368 to 500 by subtracting.
500 - 368 = 132
Now, we need to get it in word form. This can be done by looking at the place value of each number.. So your answer would be:
1 hundred, 3 tens, and 2 ones.
1 in 13 or 1/13 because those are the only numbers it gives you and since he only sold one vanilla cone in the last thirteen cones you can only assume that he sells one vanilla every 13
