Найдите число x, для которого равенство верно:

79 : x = 718

x  12 = 12

1225 : x = 35

79:х = 718              х:12 = 12               1225:х = 35

7*х = 79*18             2 х = 1*12                       3х = 1225 * 5

х = 147                      х = 12 :2                        х = 125

х =2                            х = 14                            х = 2,4

                                   х = 0,25
