Respuesta :

Recall that a full turn has 360°, therefore, to answer this question, we have to compute the 25% of 360.

Now, to compute the x% of y, we can use the following expression:

[tex]\frac{x}{100}\times y\text{.}[/tex]

Using the above expression, we get that the 25% of 360 is:

[tex]360\times\frac{25}{100}=90.[/tex]

Answer:

[tex]90.[/tex]
