Algebraic Expressions In Chapters 6-9 (CPA)

855 Words2 Pages

We studied various math concepts throughout chapters 6 through 9 in CPM. Why are those topics connected? When we make connections through each of these different topics, it can help us learn and understand these topics more. Some of these concepts we learned throughout the year were things such as dividing fractions, algebraic expressions, statistical data, distance, rate, and time, volume, and percents were all the topics we studied in these chapters.

Dividing fractions are similar to portions of portions. You can divide fractions by just flipping the numerator and denominator of the second fraction and then multiplying straight across, but why does this work? This works because division and multiplication are inverse operations. …show more content…

Terms are single numbers or variables. Factors are things that can be multiplied together, to get the same number. Lastly, coefficients are a multiplicative or factor. Now how do we solve these? Well, if you use the order of operations or pemdas, you can solve them. In Pemdas, p stands for parenthesis, e is exponents, m is for multiply, d is for divide, a is for add, and s is for subtract. To do this you can solve algebraic expressions, such as the one down below. You can also use terms and factors in statistical …show more content…

How do we find these? Well to find distance, you do rate times time. For example, If the train was going at rate of 2 miles per 5 minutes, you would multiply 2 and 5 together to get a total distance of 10. How do we get the average rate? To find rate, you do distance divided by time. For example, if the distance was 10 , and the time was 5 minutes, you would do 10 divided by 5, to get a rate of 2 miles per 5 minutes. Last but not least is time. For time, you would do distance divided by the rate. An example would be if the distance was 10, and the rate was 2, you would do 10 divided by 2, to get 5 as the time. You can use things like the length or distance of something when finding volume was
