# Math Help - Help! Need someone to explain

1. ## Help! Need someone to explain

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.

2. The line of over the 3 in the decimal means it is repeated or as you out it $\frac{33.333333.....}{10}$ and goes on and on and this reduces to $33\frac{1}{3}$

Your second one is right maybe your teacher wanted it in fraction form though which would be $11\frac{1}{3}$

$3(33\frac{1}{3})=100$ 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.

3. But its $-\left(\frac{-654.796}{-100}\right)$
