Problem 3
Ben wrote the mixed number
$$7\frac{1}{3}$$
as a fraction. Here is his work:
{"table": [{"_attributes": {"align": "center", "class": ["table", "table-bordered"], "style": "width:40%"}, "tbody": [{"tr": [{"td": [{"_attributes": {"style": "text-align:center"}, "span": [{"_attributes": {"class": ["math-tex"]}, "_value": "$$7\\frac{1}{3}= 7 + \\frac{1}{3}$$"}]}, {"_value": "(Step 1)"}]}, {"td": [{"_attributes": {"style": "text-align:center"}, "span": [{"_attributes": {"class": ["math-tex"]}, "_value": "$$=\\frac{7}{1}+\\frac{1}{3}$$"}]}, {"_value": "(Step 2)"}]}, {"td": [{"_attributes": {"style": "text-align:center"}, "span": [{"_attributes": {"class": ["math-tex"]}, "_value": "$$=\\frac{21}{3}+\\frac{1}{3}$$"}]}, {"_value": "(Step 3)"}]}, {"td": [{"_attributes": {"style": "text-align:center"}, "span": [{"_attributes": {"class": ["math-tex"]}, "_value": "$${={22\\over3}}$$"}]}, {"_value": "(Step 4)"}]}]}]}]}
