NiCoLe'S sUpEr ScRiBe PoSt....

What is "FRACTION" ?
- A fraction is a number written in the form: N/D. Where N is called "NUMERATOR" and D is called the "DENOMINATOR".
- It also expresses part of a group.
-If the fractions have the same denominator, their sum is the sum of the numerators over the denominator. We do not add the denominators. But we can reduce it if necessary.
Examples:
3/8 + 2/8 = 5/8
- However, if the fractions have different denominators:
1) First, find the Least Common Denominator or LCD.
2) Then write equivalent fractions using this denominator.
3) Add the fractions. Reduce if necessary.
Example:
3/4 + 1/6 = ?
The Least Common Denominator(LCD) is 12.
3/4 + 1/6 = 9/12 + 2/12 = 11/12.
Example:
2/3 + 2/7 = ?
The Least Common Denominator(LCD) is 21
2/3 + 2/7 = 14/21 + 6/21 = 20/21
