The answer is B. 3/4
36/48 both share the common factor of 12, divide 12 by the numerator and denominator to get the simplified fraction, 3/4
Alice has read 150 pages, you would multiple 200 by .75 (75%). If Nina had read 50% of her book and she read 150, you multiple by 2, and get 300. So Nina has 300 pages in her book.
Your answer is D
hope this helps
