Question

Dacă a+3=6×b=c×2=84.Aflați produsul numerelor a,b şi c.

Answer 1

a+3=6b=>a=6b-3
6b=2c=>b=2c/6
2c=84=>c=84/2=>c=42
b=2c/6=>b=2*42/6=>b=14
a=6b-3=>a=6*14-3=>a=84-3=>a=81
a*b*c=81*14*42=47628

Answer 2

a + 3 = 6 × b = c × 2  = 84 

a + 3 = 84 
a = 84 - 3 
a = 81 

6 × b = 84 
b = 84 : 6 
b = 14 

c × 2 = 84 
c = 84 : 2 
c = 42 

81 × 14 × 42 = 1 134 × 42 = 47 628 → produsul numerelor 

81 + 14 + 42 = 137 → suma numerelor
