Answer 2

I can help you with your math problem.

The problem is: A girl read 3 times less pages than she had left to read. There are 174 pages in the book. How many pages did the girl read?

To solve this problem, we can use the following steps:

1. Let x be the number of pages that the girl read. Then, the number of pages that she had left to read is 3x, because it is 3 times more than what she read. 2. The total number of pages in the book is 174, so we can write an equation: x + 3x = 174. This means that the sum of the pages that the girl read and the pages that she had left to read is equal to the total number of pages in the book. 3. To find x, we need to simplify the equation. We can do this by adding the terms with x on the left side: 4x = 174. Then, we can divide both sides by 4 to isolate x: x = 174 / 4 = 43.5. This is the number of pages that the girl read. 4. To check our answer, we can plug x = 43.5 into the original equation: 43.5 + 3 * 43.5 = 174. This is true, so our answer is correct.

Therefore, the girl read 43.5 pages. I hope this helps you understand the problem better.
