Answer 2

Calculating the Number of Pages Read by the Girl

To calculate the number of pages read by the girl, we can use the given information that the girl read three times fewer pages than the number of pages she has left to read, and the total number of pages in the book is 176.

Let's denote the number of pages the girl has read as x and the number of pages she has left to read as y.

According to the given information, we have the equation: x = 3y (The girl read three times fewer pages than she has left to read)

We also know that the total number of pages in the book is 176: x + y = 176

Solving the Equations

We can solve these two equations to find the values of x and y.

Substituting the value of x from the first equation into the second equation: 3y + y = 176 4y = 176 y = 44

Now that we have the value of y, we can find the value of x: x = 3y x = 3 * 44 x = 132

Answer

The girl read 132 pages of the book.
