1) $\frac389 + \frac173 - \frac139 = \frac389 + \frac519 = \frac899 - \frac139 = \frac769 = 8,4$

НОЗ: 9.

2) $9 - \frac7017 + \frac3717 = -\frac7017 + \frac3717 = \frac10717 = 9 - 6,29 = 2,71$

3) $\frac285 - \frac2811 + \frac185 = \frac30855 - \frac14055 = \frac16855 + \frac19855 = \frac36655 = 6\frac3655$

НОЗ: 55.

4) $\frac358 + \frac318 - \frac107 = \frac668 - \frac107 = \frac46256 - \frac8056 = \frac38256 = 6\frac4656$

НОЗ: 56.

5) 20 - $\frac5315 + \frac15415 = \frac20715 = 20 - 13,8 = 6,2$

6) 30 - $\frac15910 - \frac12310 = \frac3610 = 30 - 3,6 = 26,4$

7) $\frac17211 - \frac7316 + \frac3711 = \frac2752176 - \frac803176 = \frac1949176 + \frac3711 = \frac1949176 + \frac592176 = \frac2541176 = 14,4375$

НОЗ: 176.

8) 49 - $\frac985 - \frac125 = \frac865 = 49 - 17,2 = 31,8$

9) $\frac16013 - \frac5320 + \frac4813 = \frac3200260 - \frac689260 = \frac2511260 + \frac4813 = \frac2511260 + \frac960260 = \frac3471260 = 13,35$

НОЗ: 260.

10) $\frac50417 - \frac10124 + \frac17617 = \frac12096408 + \frac1717408 = \frac13813408 = 33,85$

НОЗ: 408.
