A) 5/7 + 9/2 =(5x2)/(7x2)+(9x7)/(2x7)=10/14+63/14=73/14
b) 6/4x3/5-13/20=(6x3)/4x5)-13/20=24/15-13/20
=(24x4)/(15x4)-(13x3)/(20x3)=96/60-39/60
= (96-39)/60=57/60=19/20
c)18/11+(5/6)x3=18/11+15/6=(18x6)/(11x6)+(15x11)/(6x11)
= 108/66+165/66=273/66=91/22
d)( -12/100)x(40/10)+480/1000=(-48/1000)+(480/1000)
= (480-48)/1000=432/1000=216/500
=108/250=54/125
