Question

si a/b = c/d donde a+b=60 c= 3 d=2. Calcule a y b

Answer 1

a/b = c/d = k

Además:

a + b = 60

c = 3

d = 2

Luego:

a/b = c/d = k

Entonces:

a/b = 3/2 = k

a = 3k

b = 2k

Si: a + b = 60 [Reemplazando]

⇒ 2k + 3k = 60

5k = 60

k = 60/5

k = 12

Finalmente:

a = 3k = 3(12) = 36

b = 2k = 2(12) = 24
