I have attached a few problems with this note. We had a quiz last week and I missed a few problems and don't understand why. Please advise.

The line of over the 3 in the decimal means it is repeated or as you out it $\displaystyle \frac{33.333333.....}{10}$ and goes on and on and this reduces to $\displaystyle 33\frac{1}{3}$
Your second one is right maybe your teacher wanted it in fraction form though which would be $\displaystyle 11\frac{1}{3}$
$\displaystyle 3(33\frac{1}{3})=100$ Try converting into fractions and doing the math it will help.
Your fourth is also right I don't know why it was marked wrong.
Your fifth is right too.
