Multiplying Fractions

 
 Multiplying fractions together is pretty easy. 
 When you multiply them, you just multiply the numerators (numbers on top) 
 and the denominators (numbers on the bottom).
 

 
 If the 2 fractions you multiply together are both less than 1, 
 the answer is also less than 1. 
 IN FACT, 
 if the 2 fractions you multiply together are each less than 1, 
 
 the answer you get will be less than either of the fractions 
 you multiplied together! 
 Watch:
 

 

 
 Some people have a hard time with fraction math. 
 Mostly because of the different ways 
 the denominator (bottom part) gets treated. 
 In addition and subtraction, the denominators must be the same. 
 In multiplication, they don't. 
 In addition and subtraction, the denominator isn't touched. 
 In multiplication the denominator almost always changes.
