Verified answer

$\frac{35*28+35*32}{60*15} = \frac{35(28+32)}{60*15} = \frac{35*60}{60*15} = \frac{35}{15} = \frac{7}{3} \\
 \frac{57*62-57*34}{28*19} = \frac{57(62-34)}{28*19} = \frac{57*28}{28*19} = \frac{57}{19} =3$

natalyvd (35*28)+(35*32)/60*15=35*(28+32)/60/15=35*60/60*15=35/15=7/3=2 1/3

(57*62)-(57*34)/28*19=57*(62-34)/28*19=57*28/28*19=57/19=3
