Tres hermanos van a repartirse un pastel y medio, cuanto le toco de pastel a cada uno de los hermnos

Anna71 [15]

Answer:

medio pastel cada uno

Step-by-step explanation:

Hay 3 hermanos, si decimos que un pastel entero tiene 6 pedazos entonces su fraccion seria 6/6. Si dividimos este pastel entre los tres hermanos cada uno tendria...

$\frac{6 / 3}{6}$ = $\frac{2}{6}$

Medio pastel seria la mitad de 6/6 que seria 3/6. Si dividimos esto entre los 3 hermanos cada uno tendria...

$\frac{3 / 3}{6} = \frac{1}{6}$

Ahora que dividimos los 2 pasteles tenemos que unir las fracciones para saber cuanto pastel le toco a cada hermano...

$\frac{2}{6} + \frac{1}{6} = \frac{3}{6}$ o medio pastel cada uno

To draw a line segment perpendicular to XY passing through point x

Andrew [12]

What does perpendicular mean? Well, in elementary geometry it mean 2 lines that intersect at a right angle. (90°).

So for Part one. all you need to do is draw a straight line down from the point X. Name the end point of that line M.

Now you will connect the line M and Z.

Thats it! I hope this helped!! :)
