Round up--------> 
therefore
the answer is

495 possibilities
multiply 165 and 3
M•8=142 is the equation i believe
Remember
(a/b)/(c/d)=(a/b)(d/c)=(ad)/(bc)
convert to improper fractions
8 and 1/2=8+1/2=16/2+1/2=17/2
2 and 1/4=2+1/4=8/4+1/4=9/4
8 and 1/2 divided by 2 and 1/4=
(17/2)/(9/4)=
(17/2)(4/9)=
(17*4)/(2*9)=
68/18=
34/9=
27/9+7/9=
3+7/9=
3 and 7/9
