Question

Calcula, en las siguientes fracciónes, el término desconocido, para que sean equivalentes:

3/7 = x/42 = 24/x

x/4 = 27/36 = x/24

Answer 1

La hacemos por partes:

3/7 = x/42 = 24/x

3/7 = x/42
42*3/7 = x;  simplificando la septima:
x = 9*3
x = 18


3/7 = 24/x
x = 24*7/3; simplificando la tercera:
x = 8*7
x = 56


3/7 = x/42 = 24/x
3/7 = 18/42 = 24/16

SEGUNDO EJERCICIO

x/4 = 27/36 = x/24


x/4 = 27/36
x = (27*4)/36; simplificando la cuarta
x = 27/9
x = 3


27/36 = x/24
(27*24)/36 = x; simplificando la novena
x =(3*24)/4; simplificando la cuarta
x = 3*6
x = 18


x/4 = 27/36 = x/24
3/4 = 27/36 = 18/24
