I did not give the answers for question 8 and 9. But I believe that you should be able to get the answers if you understand the models I've drawn.

mary’s share is 2/3 of nell’s share.
for easy understanding:
circle numerator , arrow to marry
circle denominator , arrow to nell.
so mary has 2u
nell has 3u.
nell’s share is 1/2 of tory’s share.
circle and arrow ,
nell has 1 u
tory has 2u
x3 to each of them so that its easy to compare,
nell has 3 u , tory has 6u , mary remains same, mary has 2 u.
so question wants mary share over tory share
2/6 fraction
