Answer: 1.19

Explanation:


\displaystyle\\(3(1)/(2)-1(4)/(5) )/(1(3)/(7) )=\\\\((3*2+1)/(2) -(1*5+4)/(5) )/((1*7+3)/(7) ) =\\\\((6+1)/(2)-(5+4)/(5) )/((7+3)/(7) ) =\\\\((7)/(2)-(9)/(5) )/((10)/(7) ) =\\\\((7*5-9*2)/(2*5) )/((10)/(7) ) =\\\\((35-18)/(10) )/((10)/(7) ) =\\\\((17)/(10) )/((10)/(7) ) =\\\\(17*7)/(10*10) =\\\\(119)/(100) =\\\\1.19
