2 - 1/4  =   (8/4)  - (1/4)   = 7/4

 

3 - 1/5  =    (15/5)  - (1/5)   = 14/5

 

So  

 

[ 2 - 1/4 ]                           7 / 4

_______       =               _____

[ 3 - 1/5 ]                         14 / 5

 

 

Keep the fraction in the numerator.......invert the fraction in the denominator and multiply the two......so we have

 

(7 / 4 )   (   5 / 14)   =      swap denominators

 

( 7 / 14)  ( 5 / 4)   =

 

(1 /2)  ( 5 / 4)  = 

 

5  / 8

 

 

 

(4/2)[6-(-5)3]    =

 

(2) [ 6 -  (-15) ]  =

 

(2)  [ 6 + 15 ] =

 

(2) [21 ]  =

 

42
