DON'T STRESS!!!!!!Please

Don't stress guys. I told you all this is something new. I also said that nobody knows how to work the problems like this. We will keep working problems like this tomorrow. You will be learning the old method tomorrow.


With tonight's homework you can always divide the value by the number of fives that make up the percent. To do this:
1. mark the percent given in the problem
2. Count all the 5's that make up the percent from the problem
3. Divide the value given in the problem by the number of 5's.
4. Take that number and multiply by 20 to get the final answer.

I hope this helps

1/11/12 HOMEWORK

25% of a number is 30, find the number.
20% of a number is 36.4, find the number.
10% of a number is 5, find the number.
65% of a number is 156, find the number.
85% of a number is 97.75, find the number.
60% of a number is 37.8, find the number.
45% of a number is 94.5, find the number.
30% of a number is 54, find the number.
5% of a number is 2.28, find the number.
75% of a number is 40.56, find the number.

THE IMPORTANCE OF EXPLANATION

I know you've heard for a very very long time that explaining is important. All of us know that 25 divided by 5 is 5, but because the man in the suit was not great at explaining he could not make Ma and Pa Kettle believe him. Sadly because Ma and Pa Kettle are persuasive their arguments are believeable.

RATES & UNIT RATE

Today in class we continued to talk about ratios but applied them to sentence problems. The following are all the slides from today's class.

We answered this in class before we discussed how tosolve the problems.
Most of us know how to solve these problems without realizing.
75 dollars              = ________ dollars
15 hamburgers                  1 hamburger
Treating this just like equivalent ratios, we divided both sides by 15 to find
out that each hamburger cost $5.

We answered this in class before we discussed how tosolve the problems.
Most of us know how to solve these problems without realizing.
From the first sentence the rate can be found.
7 hours    =  35 hours
4 lawns                 lawn
Again treating this just like equivalent ratios we multiplied the numerator
and denominator by 5 to get 20 lawns.

A comparison of 2 quatities.

This worksheet was handed out in class and will be added shortly.
