27) answer = 20% change
175 - 100%
140 - ___%
cross multiply and you'll get 140x100%/175 = 80%
175 - 100%
140 - 80%
-------
20% change
28) answer = 0.3125 or 31.25%
3 purple
5 orange
8 yellow
5 out of 16 balls together, the probability of selecting an orange ball is 5/16 = 0.3125

1>
175pounds-140pounds=35pounds
so,
35/175*100=20% is the answer
2>
total possible outcome=16
possible outcome = 5
so, p=5/16= 0.312
