Question

simplificar 21/3,25/50,4/18,24/63.
por favor ayuda

Answer 1

Hola. Simplificamo la fraccion.
 
21/3 = 7/1

25/50 = 5/10 = 1/5
 
4/18 = 2/8 = 1/4
 
24/63 = 8/21

Answer 2

hola aquí te dejo la simplificaciones de las fracciones

21 / 3  
A / b = (a: mcd (a, b)) / (b: mcd (a, b))
21 / 3 =
(3 * 7) / 3 =
((3 * 7): 3) / (3: 3) =
(21: 3) / (3: 3) =
7 / 1 =

7  

25 / 50  
a / b = (a : mcd (a, b)) / (b : mcd (a, b))
2^5 / 50 =
5^2 / (2 * 5^2) =
(5^2: 5^2) / ((2 * 5^2): 5^2) =
(25: 2^5) / (50: 25) =

4 / 18 = ?  
A / b = (a: mcd (a, b)) / (b: mcd (a, b))
4 / 18 =
2^2 / (2 * 32) =
(2^2: 2) / ((2 * 3^2): 2) =
(4: 2) / (18: 2) =

24 / 64 =?  
A / b = (a: mcd (a, b)) / (b : mcd (a, b))
24 / 64 =
(2^3 * 3) / 2^6 =
((2^3 * 3): 2^3) / (2^6: 2^3) =
(2^4: 8) / (64: 8) =
