Rezolvare:
1,(45)*(1/2)^3+0,3 (prima data transformam fractiile zecimale in fractii ordinare)
=un intreg si 45/99 * 1/8 +3/10 (introducem intregul in fractie)
=144/99 * 1/8+3/10 (simplificam 144 cu 8)
=18/99+3/10 (aducem la acelasi numitor comun)
=(180+297)/990
=477/990 (simplificam prin 3)
=159/330
=53/110
=0,4(81)
