12-(1/2+2/3)

Question

I need to know the simplest way to add to learn how to add fractions

Answer 1

Hi Ida,

 

The simplest way would to practice multiplying and combining fractions.

 

Looking at your problem, you should know immediately that the LCM would be 6 and know to multiply (1/2) by (3/3) and to multiply (2/3) by (2/2). It takes practice, but then that would be the simplest way.

 

12 - (3 / 6 + 4 / 6)

 

12 - (7 / 6)

 

Here our LCM would be 6, since 12 is actually 12 / 1, so we need to multiply it by (6/6), which gives us:

 

72 / 6 - 7 / 6

 

65 / 6

 

Hope this helps!
