...so 60% of the 6000 students drink coffee...that's 3,600 Java fans.
 
...and 25% of these (¼) add cream...so that's 900.

Quickly translating between various fractions and percents is important -- memorize several pairs.
 
If you are doing just fractions, "x out of y" means (x/y) and the word "of" usually means multiply.  So "1 out of 4" of ("3 out of 5" of 6000) means  (1/4)( (3/5)6000 ) = 900.
