## Example Questions

### Example Question #4371 : Algebra Ii

Simplify:       Explanation:

To add or subtract fractions, the fractions must have the same denominator.

The smallest common denominator in this case is .

After multiply both terms so that they have the same denominator.  Simply add these two terms together. ### Example Question #41 : Fractions      Explanation:

To solve this we need to first find common denominators. We do that by multiplying the first fraction by 5 on the top and bottom and the second fraction by 3 on the top and bottom.  Add these fractions together, then write it as a mixed number ### Example Question #42 : Fractions      Explanation:

To solve this we need to first find common denominators. We do that by multiplying the first fraction by 3 over 3. Add these fractions together, then reduce it to get the final answer. ### Example Question #43 : Fractions      Explanation:

To solve this we need to first find common denominators. We do that by multiplying the first fraction by 7 over 7 and the second fraction by 5 over 5.   ### Example Question #7 : Subtraction With Fractions

Subtract these fractions:      Explanation:

To solve this we need to first find common denominators. We do that by multiplying the first fraction by 2 over 2 and the second fraction by 3 over 3.  Subtract these fractions to get the final answer. ### Example Question #11 : Adding And Subtracting Fractions

Subtract these fractions:      Explanation:

To solve this we need to first find common denominators. We do that by multiplying the first fraction by 3 over 3 and the second fraction by 5 over 5.  Subtract the numerators of the fractions to get the final answer. ### Example Question #31 : Operations With Fractions      Explanation:
