Выполните по действиям 31,5 - ( 15,6 +16,95+29,7) * 36/83 + ( 88 1/15 - 85 19/30): 1/3

31,5 - ( 15,6 +16,95+29,7) * 36/83 + ( 88 1/15 - 85 19/30):1/3 = 11,8
1) 15,6 + 16,95 = 32,55
2) 32,55 + 29,7 = 62,25
3) 88 1/15 - 85 19/30 = 88 2/30 - 85 19/30 = 2642/30 - 2569/30 = 73/30 = 2 13/30
4) 62,25 * 36/83 = 62 25/100 * 36/83 = 6225/100 * 36/83 = 75/25 * 9/1 = 675/25 = 27
5) 2 13/30 : 1/3 = 73/30 * 3/1 = 219/30 = 73/10 = 7,3
6) 31,5- 27 = 4,5
7) 4,5 + 7,3 = 11,8
