Answer 1

$1. 3 \frac{1}{3}: \frac{2}{3}* \frac{1}{5}= \frac{10*3*1}{3*2*5}=1$
$2. \frac{4}{5}* 2\frac{1}{2}:6= \frac{4*5*1}{5*2*6} = \frac{1}{3}$
$3. 3 \frac{1}{5}* \frac{5}{8}: \frac{2}{7}= \frac{16*5*7}{5*8*2}=7$
$4. 26:3 \frac{1}{4}* \frac{1}{16}= \frac{26*4*1}{1*13*16}= \frac{1}{2}$

Answer 2

1)3 1/3:2/3*1/5=10/3*3/2*1/5=5*1/5=1
2)4/5*2 1/2:6=4/5*5/2*1/6=2*1/6=1/3
3)3 1/5*5/8:2/7=16/5*5/8*7/2=2*7/2=7
4)26:3 1/4*1/16=26*4/13*1/16=8*1/16=1/2
