MArishka [77]

Respuesta:

A.) BA = 12 m

Explicación paso a paso:

Usando triángulos similares:

BA / AC = DE / EC

BA = x; AC = 20; DE = 3; EC = 5

POR ESO ; TENEMOS :

x / 20 = 3/5

Multiplicar en cruz:

5 * x = 20 * 3

5 veces = 60

5x / 5 = 60/5

How to convert 3.248 repeating decimal with 48 repeating into a simplified fraction

Sonja [21]

Answer:

$x=\frac{536}{165}$

Step-by-step explanation:

Let X be the value of 3.2484848.... infinite times

Multiply by 100

$x=3.24848....\\100x = 324.8484.....$

Subtract to get

$100x-x = 324.8484...-3.248484....\\99x = 321.60\\x=\frac{321.6}{99} \\x=\frac{1072}{330} \\x=\frac{536}{165}$

Thus the number 3.248 repeating decimal with 48 repeating in fraction form is

$\frac{536}{165}$
