Question

Aflați numerele a b si c stiind ca: a×b×c=96 a×b= 24 b×c= 32 Votez cel mai bun

Answer 1

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
