write a problem write a word problem involving the number of pages in a book.then write the numerical expression that you would need to use to solve your problem.

Swetha is reading a book with 250 pages. She has read 120 pages. How many pages does she have left to read?

250 - 125 = ?

250 - 120 = ?

I could've said how much more instead of how many.

That would be more understanding for me.

Problem:

Maria is reading a book that has 250 pages. She has already read 70 pages. How many more pages does she need to read to finish the book?

Numerical Expression:
To solve this problem, we can subtract the number of pages Maria has already read from the total number of pages in the book:

Number of pages to read = Total number of pages - Number of pages already read
Number of pages to read = 250 - 70

Numerical Expression: 250 - 70 = 180

Therefore, Maria needs to read 180 more pages to finish the book.
