Awesome question!

1.) You have 80 points and you want to take away 5% of them.

- 5% is 1/2 of 10%. And remember your number places. So 80 has 0 in the ones and an 8 in the tens place. Move the decimal over to the left 1 time and you get 8.00 Now you have 10% of 80. And 5% is one half of 10%, so 8/2 is 4.

4 is 5% of 80. And you take away 4 from 80 and end up with 76.

Hope I explained this for ya!
