Question

If there are 82 students and they read 1000 books what is the average number of books the students read round it to the nearest whole number

Answer 1

12 books

Explanation:

Since there are 82 students who in total read 1000 books, we need to find how many books each student read. To do that; Divide the number of books read by the number of students who read those books. Then round your answer to the nearest whole number as an estimate. In otherwords, in "tenths place".

Step 1: Divide 1000 by 82

`1000/ 82\\\\= (1000)/(82) \\\\= 12.1951219512`

Now to round up. To round a number to the nearest whole number, you have to look at the first digit after the decimal point. If this digit is less than 5 (1, 2, 3, 4) we don't have to do anything, but if the digit is 5 or greater (5, 6, 7, 8, 9) we must round up. Since the digit after our result is less than 5, we do nothing.

Step 2: Round
`12.1951219512` in the nearest whole number

`12.1951219512 \\= 12`

Therefore, the average number of books the student read rounded to the nearest whole number is 12 books.

Answer 2

12 books read per student

Explanation:

1000 divided by 82 is close to 12
