Respuesta :

As you know, the 5 in 0.5 is in the tenths place in the number, so means
  5/10

Selection B is appropriate.

Answer:

The correct option is B.

Step-by-step explanation:

The given number is 0.5.

If a number can be defined as a/b where b≠0, then it is called a rational number.

We need to rewrite the given number in the form of a/b using integers.

Multiply and divide the given number by 10 to remove the decimal from the given number.

[tex]0.5\times \frac{10}{10}[/tex]

On simplification we get

[tex]\frac{0.5\times 10}{10}[/tex]

[tex]\frac{5}{10}[/tex]

Here a=5 and b=10 both are integers.

The given number 0.5 is a ration number because it can be written as 5/10.

Therefore the correct option is B.
