On a special two day clearance sale, 3 out of 5 books on clearance were sold on the first day of the sale. If 280 books were originally for sale on clearance how many were sold on the first day of the sale?

168 books

Step-by-step explanation:

According to problem, given data are as follows:

Total books for sale = 280 books

Sold on first day = 3 out of 5 books

So, percentage of first day sold = 3 ÷ 5 = 0.6 or 60%

So, we can calculate the total books sold on day one by using following method,

Total books sold on first day = Total books for sale × percentage sold

By putting the value, we get

= 280 books × 60%

= 168 books
