$= 49 - ( \frac{671}{27} - \frac{385}{27} + \frac{16}{39} ) + \frac{53}{13} - 26) + \frac{1}{2} = 49 - \frac{3862}{351} - \frac{285}{13} + \frac{1}{2} = \frac{895}{54} = 16 \frac{31}{54}$

hhulievgmailcom Здравствуйте я думаю ,что у вас неправильно

hhulievgmailcom 1) 61 11/27-35 11/27=26
2) 26+1 16/39=27 16/39
3) 53 1/13-52 1/2=15/26
4) 49-27 16/39=22 16/39
5) 22 16/39+15/26=22 77/78
6) 22 77/78+1/2=22 116/78
7) 22 116/76=38 1/78
