Hi there!
To solve this problem, we need to find the total amount of paint used by adding the two fractions.
First, we need to find the common denominators below adding.
1/2 = 2/4
1/4 = 1/4
The common denominator is 4.
Now, we add the mixed numbers together:
3 2/4 + 2 1/4 = 5 3/4
Since 5 3/4 can't be simplified, the answer is:
5 3/4 liters of paint
Hope this helps!
