/ ułamek
* mnożenie
: dzielenie

Answer 1

7/20-3/2=7/20-30/20=-23/20
2 1/4+3/16=9/4+3/16=36/16+3/16=39/16
1/4*7/10=7/40
51/50:1/100=51/50*100/1=102
7/8*1/2=7/16
3/10*18/10=54/10=5 2/5
2/1000*3/2=6/2000=3/1000
45/10-4/3=135/30-40/30=95/30=3 1/6
-35/10+11/6=-210/60+110/60=-100/60=-1 20/30
20/3*(-1/10)=-20/30=-10/15=-2/3
-12/5:-12/10=-12/5*(-10/12)=120/60=2
68/10:(-7/3)=68/10*(-3/7)= -204/70
-62/10*7/5=-434/50=-8 34/50
