a) 1/8
б) 1 1/16
Пошаговое объяснение:
1/11 * (3/4 + 5/8)=11*(6/8+5/8)= 1/11*11/8=1/8
2-(5/6:8/9)=2-(5/6*9/8)=32/16-15/16=17/16=1 1/16
а)
1/11 *² (3/4 +¹ 5/8) = 1/8
1) 3/4 + 5/8 = 6/8 + 5/8 = 11/8;
2) 1/11 * 11/8 = 1/1 * 1/8 = 1/8.
б)
2 -² 5/6 :¹ 8/9 = 1 1/16
1) 5/6 : 8/9 = 45/54 : 48/54 =45/54 * 54/48 = 45/1 * 1/48 = 45/48
2) 2 - 45/48 - 1 3/48 = 1 1/16.
