Question

Marcella read 100 books over the school year. 60 of the books were mysteries. She said the mysteries equal 0.06 of the total books. Is she correct?

Answer 1

Marcella is not correct

The mysteries equal 0.6 of the total books

Explanation:

step 1

Using proportion

Find the percentage of books that were mystery.

100 books represent the 100%

so

`(100\%)/(100)=(x)/(60) \\ \\x=100\%*60/100\\ \\x=60\%=60/100=0.6`

therefore

The mysteries equal 0.6 of the total books
