10 cm = 10/100 m = 1/10 m 15 cm = 15/100 m = 3/20 m 17 cm = 17/100 m  25 cm = 25/100 m = 1/4 m 40 cm = 40/100 m = 2/5 m 50 cm = 50/100 m = 1/2 m 63 cm = 63/100 m 90 cm = 90/100 m = 9/10 m

10/100m=1/10 15/100=3/20 17/100 25/100= 1/4 40/100= 2/5 50/100= 1/2 63/100 90/100= 9/10 / to sa kreski ulamkowe. licze na naj :)
