Question

a×b = 40 a×c = 32 b×c= 20 Aflati a, b, c​

Answer 1

Explicație pas cu pas:

b=40:a b= 40:8=5

c=32:a c= 32:8=4

b×c=5×4=20

a=8, b=5, c= 4

Answer 2

Salut! :)

a × b = 40 => a = 40/b

b × c = 20 => c = 20/b

40/b × 20/b = 32

800/b² = 32

b² = 800 : 32

b² = 25 => b = 5

a = 40/5 = 8

c = 20/5 = 4
