How many novels did Regina write last year? ** Number of novels she wrote last year = (3/4)*number of novels she wrote this year
How many novels did Regina write last year? ** 9 = (3/4)*number of novels she wrote this year
How many novels has Regina written this year? ** Multiplying both sides by 4/3 gives the number of novels she has written this year = (4/3)*9 = <<4/3*9=12>>12 novels
