22 1/3 -[10 7/12+9 11/20] =
= 67/3-(127/12+191/20)=
= 67/3-302/15=(335-302)/15=33/15=11/5
= 67/3-(127/12+191/20)=
= 67/3-302/15=(335-302)/15=33/15=11/5
67/3-(127/12+191/20)=
67/3-(635/60+573/60)=
67/3-302/15=
335/15-302/15=33/15=11/5
introducem intregii in fractie ,respectam regulile de calcul ,intai paranteza apoi aducem la acelasi numitor comun si calculam
