Question

4 2/5 : 6 - 3/4 * 1 1/5​

Answer 1

$4\frac{2}{5} :6-\frac{3}{4} *1\frac{1}{5} \\1) 4\frac{2}{5} :6=\frac{22}{5} :6=\frac{22}{5*6} =\frac{22}{30} \\\\2) \frac{3}{4} *1\frac{1}{5}=\frac{3}{4} *\frac{6}{5}=\frac{3*6}{4*5} =\frac{3*3}{2*5} =\frac{9}{10} \\\\3)\frac{22}{30} -\frac{9}{10} =\frac{22}{30} -\frac{27}{30} =\frac{22-27}{30} =-\frac{5}{30}=-\frac{1}{6}$
