Котенок050402 · Answer

((35/57 - (-29/38)) * 19/29 - (-27/34 - 48/51) * 17/29) * 87/164 = 1 целая 3/164

1) 35/57 - (-29/38) = 70/114 + 87/114 = 157/114
2) 157/114 * 19/29 = (157*1)/(6*29) = 157/174
3) - 27/34 - 48/51 = - 81/102 - 96/102 = - 177/102
4) - 177/102 * 17/29 = - (177*1)/(6*29) = - 177/174
5) 157/174 - (-177/174) = 157/174 + 177/174 = 334/174 = 167/87
6) 167/87 * 87/164 = 167/164 = 1 целая 3/164
