Explanation:

a.
`(115)/(100)*230=(26450)/(100)=264.5`

b.
`(80*4+3/4)/(100)*50=(323/4)/(100)*50=(323/4*50)/(100)=(4037.5)/(100)=40.375`

c.
`(500)/(100)*0.02=5*0.02=0.1`

d.
`(1/10)/(100)*800=1/10*1/100 *800=(1)/(1000)*800=(800)/(1000)=0.8`

e.
`(63*5+4/5)/(100)*12000=(319/5)/(100)=12000=319/5*1/100*12000=319/500*12000=(319*12000)/(500)= (3828000)/(500)=7656`

f.
`(0.05)/(100)*1000000=(0.05*1000000)/(100)= (50000)/(100)=500`
