Notice that the denominators are 3 and 7, which are factors of 21. So express all the fractions with denominator 21: On Monday [latex] \frac{1}{7} = \frac{1}{7} * \frac{3}{3} = \frac{3}{21} [/latex] are sold On Tuesday [latex] \frac{1}{3} = \frac{1}{3} * \frac{7}{7} = \frac{7}{21} [/latex] are sold On Wednesday [latex] \frac{2}{7} = \frac{2}{7} * \frac{3}{3} = \frac{6}{21} [/latex] are sold by Thursday [latex]\frac{3}{21}+\frac{7}{21}+\frac{6}{21} = \frac{3+7+6}{21}= \frac{16}{21} [/latex] of the tickets was sold. Answer: [latex]\frac{16}{21}[/latex]
