Question

1) 3 2) 2 3) 9 _ : 9 _ : 10 _ : 3 4 5 10

Answer 1

$\frac{3}{4}:9= \frac{3}{4}: \frac{9}{1}= \frac{3}{4}* \frac{1}{9}= \frac{1*1}{4*3}= \frac{1}{12}$

$\frac{2}{5} : 10= \frac{2}{5}: \frac{10}{1}= \frac{2}{5}* \frac{1}{10}= \frac{1*1}{5*5}= \frac{1}{25}$

$\frac{9}{10} :3= \frac{9}{10} : \frac{3}{1}= \frac{9}{10}* \frac{1}{3}= \frac{3*1}{10*1}= \frac{3}{10}$
