3. Jaka to liczba? 10% z 50 = 5 10% z 30 = .... 25% z 80 = .. 1% z 50 = 0,5 20% z 30 = ...... = 30% z 80 = ...... 20% z 50 = 1% z 30 = .......... = 100% z 80 = .......... = 30% z 50 = ....... 10% z 30 = 1% z 80 = 1%. z 1000 = 1 1%o z 500 = 1%o z 100 = 10%. z 1000 = 10 10% z 500 = 5%. Z 100 = 50%. z 1000 = 50 20%. z 500 = 10% z 100 = ....... =
z 50 10%=5 20%=10 30%15 z 30 10%=3 20%=6 1%=0,3 10%=3 z 500 1‰=0,5 10‰=5 20‰=10 z 80 25%=20 30%=24 100%=80 1%=0,8 z 100 1‰=0,1 5‰=0,5 10‰=1 mam nadzieje ze wszystko jest dobrze
