The local library lends an average books per day = 68.24
We know there are 7 days in a week
To find the the average number of books lent to readers in a week, we multiply the number of days in a week by average number of books per day.
let x be the average number of books per week
x= 68.24 * 7
x= 477.68
The local library lends an average of 477.68 books to readers every week.
120/143. 12 x 10 is 120, and 13 x 11 is 143. It is already in simplest form.
