1) 6/125 > 8/175 , 42/875 и 40/875 , 42 > 40
2) 727/728 < 274/273 , 2181/2184 и 2192/2184, 2181 < 2192
3) 117/121 > 113/117 , 13689/14157 и 13673/14157, 13689 > 13673

1) 17/54 + 8/81 = 51/162 + 16/162 = 67/162
2) 56/117 - 11/195 = 280/585 - 33/585 = 247/585
3) 15/56 - (58/75 - 73/120) = 15/56 - (464/600 - 365/600) = 15/56 - 99/600 = 15/56 - 33/200 = 375/1400 - 231/1400 = 144/1400= 72/700

1) 1 - 3/8 = 8/8 - 3/8 = 5/8 остаток после первого дня
2) 5/8 - 42% = 5/8 - 42/100 = 125/200 - 84/200 = 41/100 = 41% это 82 стр
3) 82 : 41% = 82 : 0,41 = 200 стр всего в книге
