(3 5/18m + 2 1/6) * 6 - 7 2/3m = 12m + 13
1) 3 5/18m * 6 = 59/18m * 6 = 59/3m = 19 2/3m
2) 2 1/6 * 6 = 13/6 * 6 = 13
3) 19 2/3m - 7 2/3m = 12m
4) 12m + 13
a) 12m + 13 = 52 при m = 3 1/4
1) 12 * 3 1/4 = 12 * 13/4 = 3 * 13 = 39
2) 39 + 13 = 52
б) 12m + 13 = 32,2 при m = 1,6
1) 12 * 1,6 = 19,2
2) 19,2 + 13 = 32,2
