Mixed Fractions to improper fractions.

  In this lesson, we're going to learn about mixed fraction into improper fraction, also we're going to learn changing the improper fraction into mixed fraction.

  Mixed fraction is like this, there's a whole number right next to the fraction.
  e.g: 3 ⅓.

 An improper fraction is the numerator is bigger than the denominator. 
 e.g: 8/4.

 When you have to change the mixed fraction into the improper fraction:
1) Multiply the whole number with denominator.
2) Add the numerator with the answer which you got from the 1).
3) Now place the answer over the denominator of the fraction part.

Our first example is change 4⅔ to an improper fraction.
1)  Multiply 4 and 3 together then add 2.
2) place this total above the denominator of 3.

 When you're changing the improper fraction to mixed fraction: 
1) Divide the numerator by the denominator to find the whole number part. 
2) Write the remainder over the denominator.

For example change 23/3 to a mixed fraction.
Divide the numerator 23 by 3 to find the whole number 7 and the remainder 2. 
Therefore, 23/3 = 7⅔.
