{"table": [{"_attributes": {"class": ["table", "table-bordered"], "style": "width:40%"}, "tbody": [{"tr": [{"td": [{"p": [{"_attributes": {"style": "margin-left:40px"}, "span": [{"_attributes": {"class": ["math-tex"]}, "_value": "$$\\frac{1}{3}$$"}], "_values": ["i.", "of 9"]}]}, {"p": [{"_attributes": {"style": "margin-left:40px"}, "span": [{"_attributes": {"class": ["math-tex"]}, "_value": "$$\\frac{2}{3}$$"}], "_values": ["ii.", "of 9"]}]}]}, {"td": [{"p": [{"_attributes": {"style": "margin-left:40px"}, "span": [{"_attributes": {"class": ["math-tex"]}, "_value": "$$\\frac{1}{5}$$"}], "_values": ["iii.", "of 10"]}]}, {"p": [{"_attributes": {"style": "margin-left:40px"}, "span": [{"_attributes": {"class": ["math-tex"]}, "_value": "$$\\frac{4}{5}$$"}], "_values": ["iv.", "of 10"]}]}]}, {"td": [{"p": [{"_attributes": {"style": "margin-left:40px"}, "span": [{"_attributes": {"class": ["math-tex"]}, "_value": "$$\\frac{1}{4}$$"}], "_values": ["v.", "of 12"]}]}, {"p": [{"_attributes": {"style": "margin-left:40px"}, "span": [{"_attributes": {"class": ["math-tex"]}, "_value": "$$\\frac{2}{4}$$"}], "_values": ["vi.", "of 12"]}]}]}]}]}]}
b.   What do you notice about the solutions to the computations in the leftmost column of the table? What do you wonder?
c.   What do you notice about the solutions in each row of the table? What do you wonder?
