Alex has read 5/6 of a book. Remaining = 1 - 5/6 = 1/6 Tina has read 3/5 of her book. Remaining = 1 - 3/5 = 2/5 For Alex: 1/6 = 150 pages, so total = 900 pages For Tina: 2/5 = 150 pages, so total = 375 pages Fraction of pages read by Alex that have been read by Tina: Pages read by Tina = 375 * 3/5 = 225 Pages read by Alex = 900 * 5/6 = 750 Fraction = 225 / 750 = 3/10
