Пошаговое объяснение:
1)3/10 + 1/100 + 4/1000 = 300/1000 + 10/1000 + 4/1000 = 314/1000 = 0,314
2)5 + 7/10 + 9/100 = 5 + 70/100 + 9/100 = 5 + 79/100 = 5,79
3)6 + 9/10 + 7/1000 = 6 + 900/1000 + 7/1000 = 6 + 907/1000 = 6,907
4)20 + 8 + 5/100 + 6/1000 = 28 + 50/1000 + 6/1000 = 28 + 56/1000 = 28,056
5)30 + 2 + 3/100 + 1/1000 = 32 + 30/1000 + 1/1000 = 32 + 31/1000 = 32,031
6)90 + 5/10 + 7/100 + 3/1000 = 90 + 500/1000 + 70/1000 + 3/1000 = 90 + 573/1000 = 90,573
