Diya finished 2/3 of a book. She calculated that she finished 70 more pages than she has yet to read. How long is her book?
Answer/Solution
A)210
Steps/Work
Let x be the total number of pages in the book, then she finished 2/3*x pages.
Then she has x−2/3*x=1/3*x pages left.
2/3*x−1/3*x=70
1/3*x=70
x=210
So the book is 210 pages long.
Answer is A.
Then she has x−2/3*x=1/3*x pages left.
2/3*x−1/3*x=70
1/3*x=70
x=210
So the book is 210 pages long.
Answer is A.
