Multiply the denominator and the whole number ( 4 x 5 ) 3 Then add the numerator ( 4 x 5 ) + 3.  23 4 5 The answer is your new numerator.   5 Your denominator stays the same. Lets try one! First we multiply 3 times 3.  (3 x 3) 2 3 3 Next we add the numerator. This gives us the new numerator. ( 3 x 3 ) + 2 = 11 Finally we use the same denominator. ( 3 ) 11 ANSWER:   3 4
  5. 5. Try these in your math notes! 1 2 4 HINT: Denominator times whole number plus numerator                                            Denominator 5 4 6 5
  6. 6. Rewriting improper fractions!! Divide 16 by 3. 5 R1 16 Write the whole number. 3  16  3 Your remainder is your numerator.     15       1 The denominator stays the same. 1 Your mixed number becomes: 5 3 6
