Keep the two the same so put 2. then you put the 2 in the faction under the division sign then you put the 5 on the outside. The answer should be 2.4.

2 2/5 = 5/5+5/5+2/5 or 12/5

to change a fraction to a decimal you use a calculator of you change it to a fraction then to a decimal

if you multiply a fraction by its recipricol (the number fliped upside down) the you will get 1 so if you multiply 1/2 by 2/1 then you will get 1

so you multiply 12/5 with 100/x=1200/5x=240

you change the percent to a fraction by moving the decimal place two places to the left or divide it by 100

so 240%=2.4 answer

Salutations!

There are 318 fiction books in the class library. The number of non fiction book is 47 less than double the number of fictions book. About how many non fiction books are there in the class library?

Let the number of non fiction books me 'NF'.

Let 'F' be fiction

Double means '2', therefore:

2F - 47 = non fiction (NF)

2(318) - 47 = non fiction

As you can see brackets indicate multiplication, therefore you will be multiplying 318 and 2

636 - 47 = non fiction (NF)

Subtract 47 from 636

589 = nonfiction (NF)

There are 589 non fiction books in the library.

Hope I helped (:

Have a great day!
