 To multiply fractional quantities tcgethtr, 



R U L E.* 



Multiply the numerators together for a new numerator, 

 and the denominators for a new denominator ; and it will 

 give the product required. 



EXAMPLES. 



1. Required to find tlie product of — and ~. 



Here ii^ii^r: — rr"^ the product reqUifcd. 

 6X9 54 27

Z. Required the product of — , — and — - — . 



jlere - — =^^ — "^^-^ — the product requirea. 



2x5X21 2io 21 



3. Required the product of — and --^ . 



Here — —— f- = •—■ — • the oroduct rcquued, 

 ex a^c ^'+^^ 



4. Required 



* I. When the numerator of one fraction, and the denomin^t* 

 or of the other, can be divided by some quantity, . which is com- 

 men to both, the quotients may be used instead cf them. 



2. When a fraction is to be multiplied by an integer, the prod- 

 uct is found by multiplying the numerator by it ; and if the inte- 

 ger be the same with the deuomioator, the numerator may be tak- 

 en for the product. 



3. When a fraction is to be multiplied by any quantity, it fs
