# SAT Practice Math Questions: Ratios

After you know the tricks, ratios are some of the easiest problems to answer quickly on the SAT Math test. Here are the points to remember:

• A ratio is written as

• A possible total is a multiple of the sum of the numbers in the ratio.

You may have to confront a proportion problem like this on the test:

At a party, the ratio of blondes to redheads is 4:5. What could be the total number of blondes and redheads at the party?

This one’s easy. Just add the numbers in the ratio: 4 + 5 = 9. The total must be a multiple of 9, such as 9, 18, 27, 36, and so on.

Now try some examples.
