Answer 1

$3 frac{2}{5} :x = 6 frac{4}{5} : 1 frac{1}{3} \ \ 6 frac{4}{5} *x= frac{17}{5} * frac{4}{3} \ \ frac{34}{5} *x= frac{68}{15} \ \ x= frac{68}{15} : frac{34}{5} = frac{68*5}{15*34} = frac{2*1}{3*1} \ \ x= frac{2}{3} \ \ 3frac{2}{5} : frac{2}{3} =6 frac{4}{5} : 1 frac{1}{3} \ \ frac{17*3}{5*2} = frac{34*3}{5*4} \ \ frac{51}{10} = frac{51}{10} \ \ 5 frac{1}{10} = 5 frac{1}{10}$
