Porównaj liczby a i b , jeśli:
a=(1-4/5)*10+(4 1/2 - 3 2/3)*3
b=(2- 1/3)*6+3*(5 1/3- 4 1/2)
Ps.: np. 1/3= ułamek zwykły

a=(5/5-4/5)*10+(9/2-11/3)*3=10/5+(27/6-22/6)*3=10/5+15/6=60/30+75/30=135/30=27/6=9/2
b=(6/3-1/3)*6+3*(16/3-9/2)=30/3+3*(32/6-27/6)=30/3+15/6=60/6+15/6=75/6=25/2
a/b=(9/2)/(25/2)=9/25
a=9/25*b
Różnica tych liczbto 8.
