Ответ №1
Пятое задание
15,25 - 4 1/6 - (5,15 - 2 2/3) = 15 3/12 - 4 2/12 - (5 9/60 - 2 40/60) =
= 11 1/12 - 2 29/60 = 10 65/60 - 2 29/60 = 8 36/60 = 8,6
1) 15,25 - 4 1/6 = 15 3/12 - 4 2/12 = 11 1/12
2) 5,15 - 2 2/3 = 5 3/20 - 2 2/3 = 5 9/60 - 2 40/60 =
= 4 69/60 - 2 40/60 = 2 29/60
3) 11 1/12 - 2 29/60 = 10 65/60 - 2 29/60 = 8 36/60 = 8 6/10 = 8,6
