I was confused here, only because I forgot the rule for multiplying fractions. I don't remember if you are supposed to solve for the LCD or multiply the denominators that were already there?-A.L.

I need help with dividing fractions. I know that I learned this before but I forgot the process. Don't you have to change the divison sign into multiplication?
Can you show me the steps in how to divide these fractions:
!/3 divided by 1/6

PLZ Help?!!!

It isn’t quite clear to me how changing things in the window changes the graph on graphing calculators. This has to do with problem 3.2 and followup.

to solve 1/3 divided by 1/6, you do have to use the oposite operation but you have to remember to use the reciprical of the second fraction. so this is how i would solve the problem:
1/3 divided by 1/6 would turn to
1/3x6/1=6/3
then you simplify=2/1 or 2

I thought that 3.2 was very very confusing. I had trouble with A and what it meant when it asked “What does each pledge plan means”. I know how to answer i.-v. but A does not make sense. So what does, for example y=-2x mean, I know how to answer it but I have no idea what pledge plan means.

On problem 3.2 I don’t understand how the graphing calculators are making the graph with the equation. Help

The thing I have trouble with is taking complex equations, (ex. 46=5+0.5d) and putting them on a graph without using a graphing calculators, as in investigation 3. I also had trouble finding the equations of graphs.

For J.B.
If the equation is y=2x+1 then that means if X equals 1 y is double that. Y=2 but it says plus one so X=1, Y=3. Then it says X=2. Y is double that which is four. Plus one equals 5 so X=2, Y=5 then this pattern is repeated and it makes a line on the coordinate graph.

A pledge plan is what the class is going to do. they will charge something like 5 dollars to start with (add-on) then you have the person who is sponsoring you pay you .50 for each mile you walk. That is a pledge plan.

In problem 3.2 I don’t fully understand question A when the book says what does each pledge plan mean. Is the problem trying to say the rate of payments for every single pledge plan?

D is the x and 46 is the y happy now you monkey face

changing the window does change the graph, but it does not change the information. you could change the # of quadrants from 1 to 4. if the last one of your coordinate points were (14,14) and the x and y intervals were _1_2_3_4, going in 1's, then your data will be spread out(farther than the origin). if the intervals were _7_14_21, going by 7's, then the data will be more scunched(closer to the origin)

To multiply fractions you Multiply the numerators of the fractions then Multiply the denominators of the fractions then Place the product of the numerators over the product of the denominators and then Simplify the Fraction

The window of the graphing calculators changes the graph because it changes how much of the graph you can see on a normal window you can see the beginning of the graph to ten if you make the window bigger you see more of the graph. Does that answer your question???????
