a × b × c = 96
a × b = 24
24 × c = 96
c = 96 : 24
c = 4
___________
b × c = 32
b × 4 = 32 ⇒ b = 32 : 4 ⇒ b = 8
_________________________
a × b = 24
a × 8 = 24 ⇒ a = 24 : 8 ⇒ a = 3
sau:
a × b × c = 96
a × 32 = 96 ( b × c = 32 )
a = 96 : 32
a = 3
__________________________
Verific: 3 × 8 × 4 = 24 × 4 = 96
Raspuns: a = 3; b = 8; c = 4
