Пошаговое объяснение:
1) (6 1/4-4 1/8)*4 + 3 1/3: 2 1/2= (25/4-33/8) *4+ 10/3 : 5/2= (50/8-33/8)*4 +
+10/3 *2/5= 17/8*4 + 4/3= 17/2 +4/3= 51/6 + 8/6=59/6= 9 5/6
2) (2 4/9+1 1/6) * 1 4/5- 3 1/9 :2 1/3=(22/9 + 7/6) * 9/5 - 28/9: 7/3=
=(44/18 +21/18)*9/5 - 28/9*3/7=65/18 * 9/5 - 4/3= 13/2-4/3= 39/6 -8/6=
= 31/6 =5 1/6
