Answer 1

(5 1/2 - 2,75): 22=2,193181818181818

100-122/3:5/6=-0,0488888888888889

Answer 2

(5 1/2 - 2,75): 22 = (5,5 - 2,75) : 22 = 2,75 : 22 = 0,125

100 - 12 2/3 : 5/6 = 100 - 38/3 x 6/5 = 100 - 76/5 = 100 - 15 1/5 = 99 5/5 - 15 1/5 = 84 4/5

2 1/5 : 3 5/8 x 56 = 11/5 x 8/29 x 56 = 88/145 x 56/1 = 4928/145 = 33 143/145

 

2 x 3,5 + 1/2 x 0.5 = 7 + 0,25 = 7,25

 

4,5 x 1 2/3 - 3,75 = 45/10 x 5/3 - 3,75 = 15/2 - 3,75 = 7 1/2 - 3,75 = 7,5 - 3,75 = 3,75
