[tex] \frac{75}{10 0} + \frac{2}{3} = \frac{225}{300} + \frac{200}{300} = \frac{425}{300} = \frac{17}{12} \\ \frac{17}{12} \times \frac{3}{17} = \frac{3}{12} = \frac{1}{4} \\ \frac{5}{10} \div \frac{1}{5} = \frac{5}{10} \times \frac{5}{1} = \frac{25}{10} = \frac{5}{2} \\ \frac{1}{4} + \frac{5}{2} = \frac{1}{4} + \frac{10}{4} = \frac{11}{4} \\ \frac{11}{4} \div \frac{6}{9} = \frac{11}{4} \times \frac{9}{6} = \frac{99}{24} = \frac{33}{8} = 4.125[/tex]
