Question

Si a/4=b/3=c/5 y a + b + c = 280 .Calcular el valor de “c - a”

Answer 1

Respuesta:

15

Explicación paso a paso:

a/4=b/3=c/5

a = 4k

b = 3k

c = 5k

a + b + c = 280

4k + 3k + 5k = 280

12k = 180

k = 15

a = 4k = 4(15)

b = 3k = 3(15)

c = 5k = 5(15)

a = 60

b = 45

c = 75

Calcular el valor de “c - a”

75 - 60 = 15
