Question

Oblicz:

8,25-10 i 3/8=

-2,25-5 i 5/6=

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

-3 i 2/3 -4=

-6,3-2,2=

2,6+ (-10)=

-0,2-(-0,7)=

-0,12- (3/4)=

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

Answer 1

1.
8.25-10 3/8= 825/100 - 83/8= 825/100 - 830/100= -5/100= -1/20
2.

-2 25/100- 5 5/6= -225/100- 35/6 = 1350/600- 3500/600=  - 4850/600=- 485/60= -8 5/60= -8 1/12
3.
1 5/6- (-1 3/8)= 1 5/6 + 1 3/8= 1 40/48+1 18/48= 2 38/48 = 2 19/24
4.
-3 2/3 - 4= -7 2/3
5.
-6.3-2.2=-8.5
6.
2.6+ (-10)= -7.4
7.
-0.2-(-0.7)= -1.3
8.
-0.12- 3/4= -12/100- 75/100=-87/100
9.
-3.35+1.1-5 1/4= -3 35/100+1 1/10- 5 1/4 = -3 35/100+1 10/100- 5 25/100= -2 25/100- 5 25/100=-7 50/100= -7 1/2
