1) 1,7 3,6 / 5,1 0,25 7,2 4
Решение:
1,7 = 17/10
3,6 = 18/5
5,1 = 51/10
0,25 = 1/4
7,2 = 36/5
(17/10) (18/5) / (51/10) (1/4) (36/5) 4
= (306/50) / (51/10) (1/4) (36/5) 4
= (306/50) / (51/10) (1/4) (36/5) 4
= (306/50) / (51/10) (1/4) (36/5) 4
= (306/50) / (51/10) (1/4) (36/5) 4
= (306/50) / (51/10) (1/4) (36/5) * 4
= 6/5
Ответ: 6/5
