a chain of bookstores sold 1 million books.group of people who bought the most books are 55yrs , bought 40%how many books did they buy?
The 55 year olds bought 40% of the book.
40% of 1 000 000.
= (40 / 100) 1 000 000
= 0.4 1 000 000
= 400 000
They bought four hundred thousand books.
I hope this explains it.
