b)
[tex] \frac{3}{4} \times \frac{17 - 1}{9} = \frac{3}{4} \times \frac{16}{9} = \frac{4}{3} [/tex]
c)
[tex] \frac{33 - 3}{9} \times \frac{3}{8} = \frac{30}{9} \times \frac{3}{8} = \frac{5}{4} [/tex]
e)
[tex] \frac{61 - 6}{90} \times \frac{6}{5} = \frac{55}{90} \times \frac{6}{5} = \frac{11}{15} [/tex]
f)
[tex] \frac{10}{7} \times \frac{326 - 32}{90} = \frac{10}{7} \times \frac{294}{90} = \frac{42}{9} [/tex]
