Explicație pas cu pas:
10.
13 : 2 = 6 rest 1
20 : 3 = 6 rest 2
15 : 7 = 2 rest 1
22 : 3 = 7 rest 1
34 : 3 = 11 rest 1
85 : 5 = 17 rest 0
_____________
11.
6 x 2 + 1 = 12 + 1 = 13
6 x 3 + 2 = 18 + 2 = 20
2 x 7 + 1 = 14 + 1 = 15
7 x 3 + 1 = 21 + 1 = 22
11 x 3 + 1 = 33 + 1 = 34
17 x 5 + 0 = 85 + 0 = 85
