Daniel has read 30​% of a book. He has 35 more pages to finish. How many pages are there in the​ book?

Answer 1

Since he hasn't read 70% of the book which is 35 pages, we need to know that 70% of what number is 35? This is called a is over of, percent over 100 proportion.

If we place 70 over 100 and set that equal 35 over x we can cross multiply and divide to find the answer.

35 times 100 = 35,000

3,500 ÷ 75 = 50
