To find the fractional portion remaining that Skyler still needs to decorate, we need to subtract the fraction he has already decorated (1/4) from the fraction he made (2/3).
Subtracting fractions requires finding a common denominator. The common denominator for 3 and 4 is 12.
So, 2/3 can be written as 8/12.
Now we can subtract 1/4 from 8/12:
8/12 - 1/4 = 8/12 - 3/12 = 5/12
Therefore, the fractional portion remaining that Skyler still needs to decorate is 5/12.
