Question

- 1 5/6 -( - 1 3/8 ) =

- 12 2/3 + 2,6 =

8, 25 - 10 3/8 =

- 2, 25 - 5 5/6 =

- 0, 12 - (- 3/4 ) =

- 3, 35 + 1, 1 - 5 1/4 =

Answer 1

-1 5/6-(-1 3/8)=-1 20/24 + 1 9/24= -11/24

-12 2/3 + 2,6= -12 2/3 + 2 3/5= -12 10/15 + 2 9/15= -10 1/15

8,25-10 3/8= 8,25-10,375=-2,125

-2,25-5 5/6= -2 1/4-5 5/6= -2 3/12-5 10/12= -7 13/12=-8 1/12

-0,12-(-3/4)=-0,12+0,75=0,63

-3,35+1,1-5 1/4=-2,25- 5,25=-7,5

Answer 2

- 1 5/6 -( - 1 3/8 ) =-11/6+11/8=-88/48+66/48=-22/48=-11/24
- 12 2/3 + 2,6 =-38/3+13/5=-190/15+39/15=-151/15=-10 1/15

8, 25 - 10 3/8 =8,25-10,375=2,125
- 2, 25 - 5 5/6 =-2 1/4-5 5/6=-9/4-35/6=-27/12-70/12=-97/12=-8 1/12
- 0, 12 - (- 3/4 ) =-0,12+0,75=0,63
- 3, 35 + 1, 1 - 5 1/4 =-3,35+1,1-5,25=-2,25-5,25=-7,5
