3.75 quarts of paint does Argelis have left with her.
<h3>What is Gallons?</h3>
A unit of volume for measuring liquids. 1 gallon = 4 quarts = 8 pints = 16 cups = 128 fluid ounces.
Here, we know that,
1 gallons = 4 quarts
so, 1/2 gallons = 1/2 X 4 = 2 quarts.
and 1/4 gallons = 1/4 X 4 = 1 quarts.
Now, total paint left with Argelis = 1/2 gallons + 3/4 quarts + 1/4 gallons
= 2 quarts + 3/4 quarts + 1 quarts
= 3 quarts + 3/4 quarts
= 15/4 quarts or 3.75 quarts
Thus, 3.75 quarts of paint does Argelis have left with her.

If Lana's age is L, her youngest sister is L/2 (or 0.5L) and the twins L-2. Add all these together (remember that there are two sisters who are L-2 years old):
0.5L + L-2 + L-2 + L = 45
Simplify the L's by adding them all together, we get:
3.5L - 2 - 2 = 45
3.5L - 4 = 45
Now add 4 to both sides:
3.5L = 49
Now divide both sides by 3.5
L = 49/3.5 = 14. Now we know that Laura is 14, so her youngest sister must be 7.
