Question

5 3/14-1 5/14+2 9/14-4 13/14

Answer 1

1) 5 3/14 - 1 5/14 = (занимаем) 4 14/14 - 1 5/14 = 3 9/14
2) 3 9/14 + 2 9/14 = 5 18/14= 6 4/14
3) 6 4/14 - 4 13/14 = (занимаем) 5 14/14 - 4 13/14 = 1 1/14

Answer 2

5 3/14 - 1 5/14 + 2 9/14 - 4 13/14 = (5 - 1 + 2 - 4) + (3/14 - 5/14 + 9/14 - 13/14) = 2 + (- 6/14) = 1 8/14 = 1 4/7
