A few unit conversions are needed to solve this problem.
Keep in mind that 2.205 lbs = 1 kg.
If 2.205 lbs = 1 kg, then 10 lbs = 22.05 kg. **Note that I multiplied 2.205 by 10 (2.205 *10 = 22.05)
Now we need to convert oz into lbs and then lbs to kilograms:
16 oz = 1 lb.
If 16 oz = 1 lb then 6 oz = 0.375 lb. **I got 0.375 by dividing 16 from 6 (6/16 = 3/8 or 0.375)
Now convert 0.375 lb to kg:
Divide 0.375 lb by 2.205 lb per kg to get 0.170 kg (0.375/2.205 = 0.170)
Bring everything you converted together.
22.05 kg + 0.170 kg = 22.22 kg --> 22.2 kg (rounded to the nearest 10th)
The gallon of paint weighs 22.2 kg.
