Answer:
Step-by-step explanation:
<u>Skills needed: Fraction Subtraction, Least Common Denominator (LCD)</u>
1) 
is the operation you would do.
--> You would do this because, Carlotta has 
of the paper left, and does one fraction amount (
) on Saturday & does another fraction amount (
) on Sunday.
--> Using subtraction is the best way
2) Now, we need to figure out the Least Common Denominator for all 3 fractions.
8,6,4 are the denominators.
The lowest number that is a factor of all them is 24.
So, it would then become 
This would become: 
(18-8-6 = 4)
So then: 
is your answer.
This simplifies into .
Hope this helps and have a nice day!! :) :]
Let 
be the number of baseball and
