To find the fraction of cookies remaining to be decorated, we need to subtract the fraction that has already been decorated from the total fraction of cookies.
The fraction that has already been decorated is 1/4.
The total fraction of cookies is 2/3.
Therefore, the remaining fraction that still needs to be decorated is 2/3 - 1/4.
To determine a common denominator, we need to find the Least Common Denominator (LCD) of 3 and 4, which is 12.
We can then write 2/3 as (2/3) * (4/4) = 8/12.
We can also write 1/4 as (1/4) * (3/3) = 3/12.
Now we have 8/12 - 3/12.
Subtracting the numerators gives us 8 - 3 = 5.
Finally, we have 5/12 as the remaining fraction that still needs to be decorated.
Skyler is making cookies to donate to the bake sale at his local grocery store. He makes 2/3 of the cookies on a given night and has only enough time to decorate 1/4 of them. What is the fractional portion remaining that he still needs to decorate?(1 point)
