Something is strange in the wording of the question. "Of the division problems, 4/9 of the problems he got incorrect. What fraction of the division problems did Gavin get incorrect?" :) Well 4/9 of course. One statement answers another. Maybe they wanted the fraction of those wrong answers were in relation to the entire test???
[tex] \frac {3}{8} * \frac {4}{9} = \frac {12}{72} = \frac {1}{6} [/tex]
