Răspuns:
Explicație pas cu pas:
a/b = 24/11 ⇒ 11 a = 24 b → produsul mezilor = produsul extremilor
a/24 = b/11 = k → coeficient de proportionalitate
a/24 = k ⇒ a = 24 k
b/11 = k ⇒ b= 11 k
_________________
a + b = 15
24 k + 11 k = 15
35 k = 15
k = 15/35 ⇒ k = 3/7
___________________
a = 24 × 3/7 ⇒ a = 72/7
b = 11 × 3/7 ⇒ b = 33/7
_____________________________________________________
Verific:
a + b = 72/7 + 33/9 = 105/7 = 15
