Пошаговое объяснение:
9 1/2 : 1,9 - 4 1/5 (6 + 7 1/2) : 15
------------------------- + ---------------------- = 0,5
2,32 * 15/29 + 4/5 (1 7/15 + 1/3) * 5
1) 9 1/2 : 1,9 = 19/2 : 19/10 = 19/2 * 10/19 = 10/2 = 5
2) 5 - 4 1/5 = 4 5/5 - 4 1/5 = 4/5
3) 2,32 * 15/29 = 232/100 * 15/29 = 8/20 * 3/1 = 24/20 = 1 4/20 = 1 1/5
4) 1 1/5 + 4/5 = 1 5/5 = 2
5) 4/5 : 2 = 4/5 * 1/2 = 4/10 = 0,4
6) 6 + 7 1/2 = 6 + 7,5 = 13,5
7) 13,5 : 15 = 13 1/2 : 15 = 27/2 * 1/15 = 9/2 * 1/5 = 9/10 = 0,9
8) 1 7/15 + 1/3 = 1 7/15 + 5/15 = 1 12/15 = 1 4/5
9) 1 4/5 * 5 = 9/5 * 5 = 9
10) 0,9 : 9 = 9/10 * 1/9 = 1/10 = 0,1
11) 0,4 + 0,1 = 0,5
