3(23) really means 3*23, or just 3 multiplied by 23.  For example: "Jana has 23 dollars.  Her friend John has $23, and his friend Jacob also has 23 dollars.  How much money do they have all together?"  To solve this problem mentally, you could break 3*23 into two numbers you're familiar with multiplying, like 20 and 3, and then add the numbers together.  For example: 3*20 + 3*3.  3*20=60, 3*3=9, and 60+9=69.  So, 3*23=69.

Claudia tiene 3/6 de un
KengaRu [80]

En este problema simplemente tenemos que usar la suma de fracciones.

Veremos que entre ambos tienen un frasco entero de miel.

Sabemos que Clauida tiene 3/6 de un frasco de miel, y el hermano tiene 9/18 de un frasco de miel.

En total, entre ambos, tienen:

3/6 + 9/18

Para poder realizar esta suma tenemos que tener el mismo denominador en ambas fracciones, asi que podemos simplificar.

en 9/18 si dividimos numerador y denominador por 9 obtenemos:

9/18 = 1/2

en 3/6 si dividimos numerador y denominador por 3 obtenemos:

3/6 = 1/2

Así:

3/6 + 9/18 = 1/2 + 1/2 = 1

Entre ambos tienen un frasco entero de miel.
