Unit Rate with rounding

When you are doing unit price you are trying to figure out how much for one item. To do this you need to divide.

But sometimes when you divide you get this REALLY BIG DECIMAL NUMBER!!! (MRS. STEIGERWALT HELP!!!) Divide $2.98 by 15.5 = 0.192258065 : (

So first you need only three places after the decimal. 3 - 1, 2, 3. Forget about the rest. Cover it up with your thumb if you need to on your calculator. So our number 0.0192258065 - becomes 0.019. Then that number in the thousandths place the 9 he tells the hundredths what to do. So you get 0.02.

1.)  $13.57  $\div$  12 = 
2.)  $115.63  $\div$  25 =
3.)  $2.24  $\div$  9.75 =
4.)  $11.16  $\div$  3 = 
5.) $53.79  $\div$  12.3 =
