Question

What is a simple rule for adding and subtracting like fractions

Answer 1

Here is you're answer:

One of the most simple rules when solving fractions is to "find the common denominator."

Example:

• $\frac{1}{2} + \frac{1}{2} =$
• Find the common denominator:
• Common denominator is 2:
• $1 +1=2$
• $= \frac{2}{2} = 2$

So, in order to solve fractions you first have to find the common denominator of each fraction, then you have to add or subtract the numerators to equal you're answer.

Mixed Numbers:                                        

1 1/2 + 1/5          Convert 1 1/2 to an improper fraction                    

3/2 + 1/5            Find the common denominator

15/10 + 2/10      Add 15/10 to 2/10

17/10                  Turn to mixed or keep to improper

Answer:  1 7/10
