$1)\frac{1}{3} \times \frac{6}{13} \times \frac{38}{2} = \frac{2}{13} \times \frac{38}{2} = \frac{38}{13}$

b)

$\frac{5}{4} \times \frac{8}{15} \times \frac{5}{9} = \frac{2}{3} \times \frac{5}{9} = \frac{30}{9}$

c)

$\frac{6}{7} \times \frac{7}{5} \times 15 = \frac{6}{5} \times 15 =6 \times 75 = 450$

d)

$6 \times \frac{5}{12} \times \frac{4}{3} = 6 \times \frac{5}{9} = \frac{54}{9} \times \frac{5}{9} = \frac{270}{9}$
