Explanation NO Good

I don’t understand why teachers on youtube are better than teachers in school. Teachers in school should teach better especially we are paying the tuition! Plus, the book they recommend is freaking suck and hard to understand no matter how you read it. That’s why i hve to spend time watching on youtube instead. I ended up learning on youtube than in class.

For the 422 decigrams to grams to milligrams solution, it should have been:

422 decigrams x 0.1g = 42.2 g

You wrote

422 decigrams x 1g

This is around 8:31
