[tex]7* \frac{4}{37}= \frac{7}{1}* \frac{4}{37} = \frac{28}{37} [/tex]

[tex] \frac{7}{15}*3= \frac{7}{15}* \frac{3}{1}= \frac{7}{5}* \frac{1}{1}= \frac{7}{5}=1 \frac{2}{5} [/tex]

[tex] \frac{8}{15}*26= \frac{8}{15}* \frac{26}{1}= \frac{208}{15}=13 \frac{13}{15} [/tex]

[tex]3 \frac{3}{8} * \frac{7}{9}= \frac{27}{8}* \frac{7}{9}= \frac{3}{8}* \frac{7}{1}= \frac{21}{8}=2 \frac{5}{8} [/tex]
