- Ok, lets start with adding fractions. If Uncle Jan weight before pandemic was 84 1/6 kg and now he gained 5 2/5 kg this month. What is Uncle Jan's weight now?
- Correct! Let's do subtracting fractions, then.
- 1/2 + 1/4 =
- Dad, I will add 84 1/6 kg and 5 2/5 kg because your question means that Uncle Jan weight is now heavier. So, 84 1/6 kg + 5 2/5 kg =84 5/30 + 5 12/30 = 89 17/30 kg

- 1/2 + 1/4 =
- Good job Charlz, your doing great in your lesson, keep it up!
- Dad, there is 1 1/2 kilograms of pork left that mama will return to the freezer.
