Question

3 1/5:(3/7-1 4/5)-4/3*2=

Answer 1

$3 \frac{1}{5} : ( \frac{3}{7} -1 \frac{4}{5} ) - \frac{4}{3} *2 =$ $= \frac{16}{5} : (\frac{15}{35} -\frac{63}{35}) - \frac{8}{3} =$ $= \frac{16}{5} : (-\frac{48}{35} ) - \frac{8}{3} =-\frac{16*35}{5*48} - \frac{8}{3} =-\frac{7}{3} - \frac{8}{3} = -\frac{15}{3} =-5$
