Given

11/12 - ⅔

Subtract the fractions.

Solution:

In order to subtract the fractions, we must first determine the LCD or the least common denominator. In our case, we have 12 and 3, and since we know that 3  is a factor of 12, therefore 12 is the LCD. Now to equate both fractions to have a common LCD, we simply multiply ⅔ by 4/4.

= (⅔)(4/4)

= 8/12

= 11/12 - 8/12

= 3/12

= ¼

Final answer:

= ¼
