Answer:

The ratio of mystery books to the total is 5/12

Step-by-step explanation:

Let

x -----> the number of Mystery books that Salvador has read

y -----> the total number of books that Salvador has read

The ratio of mystery books to the total is equal to

[tex]\frac{x}{y}[/tex]

we have

[tex]x=10[/tex]

[tex]y=10+7+5+2=24[/tex]

substitute

[tex]\frac{10}{24}[/tex]

Simplify

[tex]\frac{5}{12}[/tex]

Convert to percentage

[tex]\frac{5}{12}=0.4167*100=41.67\%[/tex]

That means

For every 12 books that Salvador reads, 5 are of Mystery

or

The number of Mystery books that Salvador has read represent 41.67% of the total number of books that Salvador has read

Answer:

[tex]\frac{10}{24} = 0.42[/tex]          

Step-by-step explanation:

By the table information,

The number of Mystery books Salvador has read = 10

And, the total number of books he read = 10 + 7 + 5 + 2 = 24

Thus, the ratio of Mystery book to the total =  [tex]\frac{10}{24} = 0.42[/tex]

It means Salvador reads 10 books in every 24 books.

Also, he read 42% of Mystery books.

It also means he like Mystery type of books over any other type of books.
