  12. To express amixed numberas animproper fraction,first multiply the whole number by thedenominator and add the numerator. Then write this sum over the denominator.

  13. 2 2x2+ 1 = = 2 2 2

  14. 2

  15. To express animproper fractionas amixed number, divide the denominator into the numerator.

  16. 2 2 3 2 = 3 3 -6 2

  17. Express the mixed number as an improper fraction. 3 x 5 + 1 = = 5

  18. Express the mixed number as an improper fraction. 5 x 9 + 8 = = 9

  19. Express the improper fraction as a mixed number. 6 = = -18 1
