2,75 : 1,1
7,236 : 2,01
1 1/3 * 0,5
-0,75 + 1 2/3
5,25 : (-1 1/2)
-5 1/5 - 3,1
-2 1/15 - (-1,3)
-1,5 : ( - 2 1/3)
proszę o rozwiązanie ;)

a- 2,31

2,75 : 1,1 = 2,5
7,236 : 2,01 = 1,1124..
1 1/3 * 0,5 = 4/3 * 5/10 = 20/30 = 2/3
-0,75 + 1 2/3 = - 75/100 + 5/3 = - 225/300 + 500/300 = 275/300
5,25 : (-1 1/2) = 525/100 :( -3/2 )= 525/100 * ( - 2/3) = 1050/300 = 3 150/300 = 3 1/2
-5 1/5 - 3,1 = - 5,2 - 3,1 = -8,3
-2 1/15 - (-1,3) = - 31/15 + 13/10 = 62/30 +39/30 = 101/30 = 3 11/30
- 1,5 : ( - 2 1/3) = - 15/10 : ( - 7/3 ) = -15/10 * (-3/7) = 45/70
2,75/1,1=2,5
7,236/2,01=3,6
1 1/3*0,5=2/3
-0,75+1 2/3=-2 125/300
5,25:(-1 1/2)=-3 25/50
-5 1/5-3,1=2 1/10
-2 1/15-(-1,3)=2 6/15
-1,5:(-2 1/3)=45/70
