John had a stock of 1,200 books in his bookshop. He sold 75 on Monday, 50 on Tuesday, 64 on Wednesday, 68 on Thursday, and 163 on Friday. What percentage of the books were not sold?

first you add up all of the sold books the subtract the sold books by the total then you divide the unsold books by the amount of books he started with then you change the decimal to a percent
75+50+64+68+163=420 1200-420=780 780/1200=.65 65%

First we have to find how many books he sold, so 75+50+64+68+163=420 - total books sold Now im finding how many books are not sold 1200-420=780 Now we can use proportion, so 1200 ---------100% 780------------x
x= x = 1200 780 ∗ 100 ​ = 65 65% of all books are not sold.

John sold 420 books out of 1,200, leaving 780 unsold. This means that 65% of the books in his shop were not sold. To find this percentage, we calculated the total sold and the total unsold and used the formula for percentage.
