  24. Remember to convert mixed numbers to top heavy fractions 1 5 3 = x

  25. Remember to convert mixed numbers to top heavy fractions 1 5 3 = x • Times the denominator • by the whole number

  26. Remember to convert mixed numbers to top heavy fractions 1 5 3 = x • Times the denominator • by the whole number • (In this case we get 5x3=15)

  27. Remember to convert mixed numbers to top heavy fractions 1 5 + 3 = x • Times the denominator • by the whole number • (In this case we get 5x3=15)

  28. Remember to convert mixed numbers to top heavy fractions 1 5 2. Add the product to the numerator + 3 = x • Times the denominator • by the whole number • (In this case we get 5x3=15)

  29. Remember to convert mixed numbers to top heavy fractions 1 5 2. Add the product to the numerator (So 15+1=16) + 3 = x • Times the denominator • by the whole number • (In this case we get 5x3=15)

  30. Remember to convert mixed numbers to top heavy fractions 1 5 2. Add the product to the numerator (So 15+1=16) + 3 = 3. Put this number over the existing denominator x • Times the denominator • by the whole number (In this case we get 5x3=15)

  31. Remember to convert mixed numbers to top heavy fractions 1 5 2. Add the product to the numerator (So 15+1=16) + 3 = 3. Put this number over the existing denominator x (In this case the denominator is 5) • Times the denominator • by the whole number (In this case we get 5x3=15)

  32. Remember to convert mixed numbers to top heavy fractions 1 5 2. Add the product to the numerator (So 15+1=16) + 3 16 5 = 3. Put this number over the existing denominator x (In this case the denominator is 5) • Times the denominator • by the whole number • (In this case we get 5x3=15)
