Answer 1

$frac{57(62-32}{28*19} = frac{57}{28}* frac{28}{19} =3$
$frac{35(28+32)}{60*15} = frac{35}{60} * frac{60}{15} = frac{35}{15} =2 frac{1}{3}$
$frac{48(31+19)}{16*100} = frac{48}{16} * frac{50}{100} =3 frac{1}{2}$
$frac{17(96-24)}{48*85} = frac{17}{48} * frac{72}{85} = frac{1}{6} * frac{9}{5} = frac{1}{2} * frac{3}{5}$
