1) = 15 + 16/60+ 35/60 + 10/60 = 15 + 61/60 = 16 1/60.
2) = 11 + 21/90 + 4/90 + 25/90 = 11 + 50/90 = 11 5/9.
3) = 8 + 9/70 + 15/90 + 18/70 = 8 + 42/70 = 8 6/10 = 8 3/5.
4) = 9 + 21/30 + 4/30 + 15/30 = 9 + 40/30 = 10 10/30 = 10 1/3.
Применяем законы:
1) ( 10 2/5 + 3 3/5) + ( 15 5/6 + 4 1/6) = 14 + 20 = 32.
2) (15 7/18 + 5/18) + (11 8/9 + 4/9) = 15 12/18 + 11 12/9 = 15 2/3 + 12 3/9 =
=15 2/3 + 12 1/3 = 28.
Это замечательные пределы, их два основных !
