Vertical stretch by a factor of 3 and a reflection over x-axis is g(x)= -3|x|
        
             
        
        
        
so , bro to multripy fractions , you have to convert the mixed fraction into unlike fractions . so lets get started.
2 3/4  *  1 1/3
= 12 / 4  * 4/3
now multiply normally 
= 48 / 12 
divide this by 4/4 to get simplest for 
= 12 / 3 divided by 3/3
= 4/1
