Răspuns:

Explicație pas cu pas:

a)

5/4 - 5/4  - 1.(5) = -1,(5)

b)

5/3 + 2/3 + 1/6 = 7/3 + 1/6 = 14/6 + 1/6 = 15/6 = 5/2

c)

5/12 + 5/6 + 1/3 = 5/12 + 10/12 + 4/12 = 19/12

d)

3/11 + 1/5 - 7/55 = 15/55 + 11/55 - 7/55 = 19/55

e)

9/4 - 5 + 11/4 = 20/4 - 5 = 5 - 5 = 0

g)

400 - 9/25 - 1/4 = 400 - 36/100 - 25/100 = 400 - 61/100 = 400 - 0,61 = 399,39

h)

1/12 + 5/6 - 1/3 - 1/4 = 1/12 + 10/12 - 4/12 - 3/12 = 4/12 = 1/3

i)

5/9 - 1/3 + 7/12 - 13/36 = 20/36 - 12/36 + 21/36 - 13/36 = 16/36 = 4/9

j)

17/7  + 1/2 - 4/5 = 170/70 + 35/70 - 56/70 = 49/70 = 7/10

k)

8/31 + 1/3 + 1 = 24/93 + 31/93 + 93/93 = 148/93
