What are the biggest problem people face when adding and subtracting fractions?

Question

How can you overcome this problem to find the correct solution?

Answer 1

Fractions is really easy... What makes it difficult is the operations... People get all mixed up with subtracting and adding fractions or even dividing or multiplying fractions. The thing you got to know is. When you add or subtract a fraction, find the common denominator. For divding fractions you will want to convert it into a multiplication fraction by the recipricol of the 2nd fraction. When you multiply fractions, you'll want to reduce first. It takes understanding before practice.

Answer 2

The common problem is looking for the LCD or least common denominator.
To overcome this, one person must know how to factor the given number. Say we got 1/12 , 1/6, the factor of 12 is 2 x 2 x 3 while the factor of 6 is 3 x 2. Combining the the two factors, since the factor of six is 3 x 2 and all present in factor of 12 then our LCD is 2 x 2 x 3 = 12, we take one at a time only number occuring more than 1.
Then practice until you become confident.

Answer 3

Remebering to get the common denominator is the most common problem. The reason is because when you multiply of divide fractions you don't need them and so one forgets. The eisiest way to overcome this is to teach adding and subtracting first so they don;t have the ideas of just going for it in their heads

Answer 4

people forget they need a common denominator when adding and subtracting fractions. You can overcome this problem with practice, practice and more practice

Answer 5

getting a common denominator would probably be most people's biggest problem. this involves searching for the least common multiple....after finding it, then you can just add or subtract as you would with regular whole numbers.

Answer 6

The most common denominator.

Answer 7

getting to the common denomenators
