Mixed numbers

Mixed numbers

1. Mixed numbers are things like 3 (1 over 3) with an integer part and a fraction part. Improper fraction are ones where the top number is larger than the bottom one.

2. Example, Write 4 (2 over 3) as an improper fraction.

   • 4 (2 over 3) = 4 + (2 over 3)
     • Addition
   • Tern the integer part into a fraction
     • 4 + (2 over 3) = (12 over 3) + (2 over 3) = (12 + 3 over 3) = (14 over 3)

3. Write (31 over 4) as a mixed number

   • Divide the top number by the bottom. 1) the answers gives the whole number part. 2) the remainder goes on top of the fraction

4. Multiplying

   • Multiply top and bottom separately. then simplify your fraction as far as possible.
     • Example
       • Find (8 over 5) x (7 over 12)
         • Multiply top and bottom separately
           • Then simplify- top and bottom both divide by 4

5. Divide

   • Turn the second fraction upside down and multiply
   • Example
     • Find 2 (1 over 3) / 3 (1 over 2)
       • Rewrite the mixed numbers as improper fraction
         • Turn (7 over 2) upside down and multiply
           • Simplify- top and bottom both divide by 7
