When surveyed, 5 out of every 8 students liked the food in the cafeteria. If 60 liked the food, how many were surveyed?
5 students out of every 8 students asked liked the food. 60 students liked the food.
This tells us that 60 students represents 5 parts of the whole. We can find out how many there are in 1 part.
1 part is 12 students. The whole is made up of 8 parts.

If 5 out of every 8 students liked the food, then the proportion of students who liked the food is ( \frac{5}{8} ).
If 60 students liked the food, we can set up a proportion to find the total number of students surveyed, ( x ):
[ \frac{5}{8} = \frac{60}{x} ]
Cross-multiplying gives:
[ 5x = 8 \times 60 ] [ 5x = 480 ] [ x = \frac{480}{5} ] [ x = 96 ]
Therefore, 96 students were surveyed.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
