Question

5/6+(-0,75)= 20/21-1/3= 31/25-0.44= -5/6*(-2,4)= 0,15:(-9/16)

Answer 1

5/6+(-0,75)=5/6-3/4=10/12-9/12=1/12

20/21-1/3=20/21-7/21=13/21

31/25-0,44=1,24-0,44=0,8
lub
31/25-44/100=124/100-44/100=80/100=8/10

-5/6*(-2,4)=-5/6*(-24/10)=120/60=2

0,15:(-9/16)=15/100:(-9/16)=15/100*(-16/9)= -240/900= - 4/15
