Answer:

20 books

Step-by-step explanation:

20% is 1/5 of 100% so the other 4/5 would be 4 times 5 which equals 20 books it total

Answer:

Mr. Brown bought 20 books.

Step-by-step explanation:

20% times 5 would be 100%. Since Mr. Brown bought 4 books, and that was 20% of all the books he bought, you would have to multiply the number of paper back books by 5 to get the answer of 100% of all books he bought, which would be 20. This problem would look like this 20(5) = 4(5), 100% = 20 books.
