Jack works in a bookstore. He has 300 books to stock on the shelves. So far, he has stocked 120 books today. What percent of the books does he have left to stock?

Answer 1

Jack has #60%# of the books left to stack.

Out of #300# books, #120# have been stacked. That leaves #(300-120)=180# books to be stacked. We can determine the percentage (#x#) by the equation:

#300xx x/100=180#

#3x=180#

Divide both sides by #3#.

#x=60#

Jack has 180 books left to stock. To find the percentage of books he has left to stock, divide the number of books left (180) by the total number of books (300), then multiply by 100. So, ( \frac{180}{300} \times 100 = 60% ). Therefore, Jack has 60% of the books left to stock.
