Question
70 % of the books on a bookshelf are History books. If there are 35 History books on the bookshelf, find the number of books on the bookshelf.
Solution
Step 1: Understand the problem. We know that 70% of the total books are History books, and there are 35 History books.
Step 2: Set up the equation. Let's denote the total number of books as X. According to the problem, 70% of X equals 35. In equation form, this is 0.70X = 35.
Step 3: Solve the equation. To find X, we need to divide both sides of the equation by 0.70.
So, X = 35 / 0.70 = 50.
Therefore, there are 50 books on the bookshelf.
