    Step-by-step explanation:

    Alicia eats 1 and 1/2 (Which means 1 cookie and a half of a cookie, or 0.5.)

    Stuart eats 2 and 1/3 (Which means 2 cookies and one third of a cookie, or 0.3333+. Basically, 1/3 means let's say you have a pie. You cut the pie into 3 separate pieces. You eat 2 seperate pieces. You have one left. You have one out of the three, which means 1/3.)

    So, you want to add both of those up.

    1 + 2 = 3

    1/2 + 1/3

    To add fractions, you have to get the denominators (Bottom number of the fraction) equal.

    So, the least common multiple (LCM) is 6.

    Why? let's lay them out.

    2: 2, 4, 6

    3: 3, 6

    These are the LEAST common multiple.

    So, you should have

    1/6 and 1/6.

    Now add the amount of times you did to the numerator (Top number)

    So, 1/2

    2 + 2 + 2 = 6

    3 times, so multiply the numerator by 3.

    1 x 3 = 3

    3/6

    So next, 1/3.

    3 + 3 = 6

    2 times, so multiply the numerator by 2.

    2/6.

    Add them both

    2/6 + 3/6 = 5/6 (Do not add denominator if they are equal)

    + 3

    3 and 5/6 cookies eaten, so

    5 - 3 5/6 = 1 & 1/6

    1 and 1/6 cookies are left on the plate.
