If there are 6 girls in a class and 12 boys in a class, what is the ratio of girls to boys in the class, in simplest form?
To find a ratio, divide the two numbers given until they are reduced to their lowest common factor, then put them into a ratio with a colon in between. Remember to order them in the way the question is asked!
6 (girls) and 12 (boys) can both be divided by 6:
For every girl, there are 2 boys in the class. Therefore, the ratio is 
.

Which ratio is "20 to 60" written in simplest form?
Which ratio is "20 to 60" written in simplest form?
- Divide both terms of the ratio by the greatest common factor. In this case, the greatest common factor is 20, because 20 is the largest number that goes into both numbers evenly.
- Show the ratio with a colon (:). Remember to keep the numbers in the correct order!
Therefore, 20 to 60 is equivalent to 1 : 3.
