* - умножить
/ - разделить

Answer 1

(( 32 * 125 + 256 * 55 ) /1130*1250 - ( 45* 76 + 98 *25 )) /1570 =
=(( 32 * 5*25 + 32*8 *5*11) /113*125 - ( 9*5* 2*38 + 2*49 *5*5)) /1570 =
=(( 160*25 + 160*88) /113*125 - ( 9*10*38 + 10*49*5)) /1570 =
=(160(25 + 88) /113*125 - 10( 9*38 + 49*5)) /1570 =
=10(16*113 /113*125 - (342+245)) /1570 =(16*125 - 587) /157 =
=(2000-587)/157=1413/157=9
