Question

The table shows the number of books Salvador has read. Find the ratio of mystery books to the total. Explain its meaning

Answer 1

`(10)/(24) = 0.42`

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 =
`(10)/(24) = 0.42`

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.

Answer 2

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

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

`(x)/(y)`

we have

`x=10`

`y=10+7+5+2=24`

substitute

`(10)/(24)`

Simplify

`(5)/(12)`

Convert to percentage

`(5)/(12)=0.4167*100=41.67\%`

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
