a. =16/3*9/4*5/4=12/1*5/4=15
b. =15/7*6/25*7/3=18/35*7/3=6/5=1.2
c. =15/11*19/6*7/25=95/22*7/25=133/110=1*23/110
e. =12/5:(17/5-26/15)=12/15:(51/15-26/15)=12/15:25/15=12/15*15/25=12/25
f. =(31/5-13/3):4/3=(93/15-65/15):4/3=28/15*3/4=7/5
g. =(11/8+17/6):5/72=(33/24+68/24):5/72=101/24*72/5=303/5=60.6
d. =10/3(11/4*2/11)=10/3*1/2=5/3
