Change the denominators to be all the same. So the fractions would be, 10/30, 6/30, and 15/30. Add the top part of the dividend together to make one big fraction. The whole thing together would be 31/30. Simplify the fraction to make, 1 and 1/30
The total amount of paint Neil has is required.
Neil has a total of [tex]1\dfrac{1}{30}\ \text{gallons}[/tex] of paint.
Amount of paint in can 1 = [tex]\dfrac{1}{3}\ \text{gallon}[/tex]
Amount of paint in can 2 = [tex]\dfrac{1}{5}\ \text{gallon}[/tex]
Amount of paint in can 3 = [tex]\dfrac{1}{2}\ \text{gallon}[/tex]
Total amount of paint
[tex]\dfrac{1}{3}+\dfrac{1}{5}+\dfrac{1}{2}[/tex]
The LCM of the denominators is 30.
[tex]\dfrac{10+6+15}{30}\\ =\dfrac{31}{30}=1\dfrac{1}{30}[/tex]
