Introduction. Here is a simple example of adding fractions: calculate + 2. 5 5. To understand this, suppose we have a cake and divide it into five equal pieces. Each piece is a fifth, or. 1 5, of the cake. If we take one fifth, and then a further two fifths, we have taken a total of three fifths: + −−. 2 3.
Cheat Sheet for Fractions. Converting Fractions: Mixed to Improper: Multiply the whole number by the denominator (bottom number) Add the numerator (top number) This number becomes the new numerator. The denominator stays the same. Example: . 5. 3 × 5 = 15. 15 + 2 = 17. 17. 5. 2. Improper to Mixed: Divide the numerator by the denominator.
5.NF.1 Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12. (In general, a/b + c/d = (ad + bc)/bd.) Supporting Standard(s ...

Fractions — basic ideas. In this unit we shall look at the basic concept of fractions — what they are, what they look like, why we have them and how we use them. We shall also look at different ways of writing down the same fraction.
As we saw in the solution in Example 7, common denominators of 6 and 4 were used for the numerator and denominator, respectively. Thus, a common denominator for both numerator and denominator would be 12. We begin the alternate solution technique by multiplying both numerator and denominator by 12. 2 1 − +.
