Answered by Ms. Sue
How else would you add and subtract fractions?


Answered by Kara
I am not sure? So you always find the LCD first?
Answered by Ms. Sue
You can use a larger common denominator, but it's simpler to use the least common denominator.

Whenever you add or subtract fractions, you must use a common denominator.

So what would an example of this be by 3/5 divided by 2/3? (using the common dinominator method)
Answered by Ms. Sue
No.

Your original question was about adding and subtracting fractions.

When you multiply or divide fractions, you do not need a common denominator.

3/5 divided by 2/3 = 3/5 * 3/2 = 9/10
