What I learned in 6th Grade
By: Caroline LaRusso
A ratio is what you use to compared two different numbers to each other. This is a ratio of the number of boy to girls in my 6th grade class and under this is just some more ratios and it will show you how to do them in the picture in the middle of the other two ratios. Ratios can also be simplified!
This time lets just show you a quick video on how to do this skill! Go to Learn Zillion and type in the search bar 614 and it will show you how to do this skill.
For rate, lets solve the problem beside this description. I will show you the steps to competing this problem below. These steps will explain to you how to do this. Rate is pretty much just a ratio (shown above) with some kind of rate in it. Here are some examples of some unit rate units.
mph or distance.
Below this is what decimals looks like. Really you can do a lot with them but you will find out all of those later.
Well... this is just a number... but we have to obviously make sure that it is negative. The first picture is WRONG and the others are right.
This is just like 4 < 5. You know about those right here is what one looks like.
This is just a prism which is a 3d shape but this 3d shape has a base that is a rectangle.
A list of numbers
I would hope you know what a list of numbers is but if you don't know how to find the three m's of the list of data here is a video and some pictures of how to do that.
Sorry I can't really explain this so here is some example below and a buzzmath link for you.
Least Common Multiple
For this you do your prime factorization and then compare the two to see what the LEAST COMMON MULTIPLE is. Here is a picture of how to do it.
