Solving proportions

I am going to solve this problem using an area model. (Please see Attachment 1). I am going to show 3/5 groups of 3 ½ by first drawing 3 wholes, and a half of the fourth whole. I am going to use a pink highlighter to show the fraction 3 ½. Each of the wholes is divided into 2 parts because the denominator shows me how many equal parts there are in a whole group. Now, I have to find 3/5 of 3 ½. I am going to break apart the entire model/amount of 3 ½ into five parts using a horizontal line and a green pen. Again, the denominator is showing me how many equal parts there are in a whole group. Horizontal line allows me to see a new denominator that is being created. My new denominator is 10 because I can see a new amount in each whole; there are 10 pieces now. Next, I have to figure out what would be the 3/5 size group of all of the model. The green loop is showing the 3/5. Then I am going to count the pieces to find out how many of them there are in the amount, which is 3/5. I can see that there are 21/10 in 3/5 groups of 3 ½. I am going to rename this fraction. To do this, I am drawing

Visual and auditory counts of animals often contain error, prompting wildlife managers use signs from animals to determine an estimated population size. Using an index population, which shows trends within the population rather than actual number, wildlife managers can determine the relative size of a population. For example, a wildlife manager can count the fecal pellets in a certain area where an animal population is inhabiting. To start the process, all of the old fecal pellets must be removed from the area. After a predetermined interval,

When examining these measurements it is observed that more whites were looked at then Hispanics or Blacks. When I give my interpretation I must then try to equal out the amount that was tested to be fair. To do so, I need to use a ratio to make sure that each sample is measured appropriately. For example, on the sample for the independent and dependent variables measured in the row total for Hispanics were 2,191,465. I then divided 80,000 by 2,191,465 to receive .037. To then get a percentage I multiplied this amount by 100 to receive a percentage of 3.6%. I had to proceed with this task in order to receive a fair amount of people measured and these are my results:

In the scientific papers, they answer these questions by similar experiments, examining the populations. One paper studied a series of island, where the islands vary between islands without deer to islands that have been populated by deer for 50 years. They studied the relationship

How do ratio’s and proportions fit into your career as a biller and coder? Please give at least three examples of when you would use them, try to give ones that differ from those already written in the discussions.

One business where ratios are used for benchmarking is Major League Baseball. “If you can’t measure it, you can’t manage it.” – Peter Drucker. Data is very important in the game of baseball and ratios maybe used more in this sport than any other. The game of baseball has many stats which are kept to determine the

He also mentions that when looking at the criteria used to discredit the use of population indices, especially relying heavily on meeting assumptions, then we would violate many more types of wildlife methods. He is also quick to say that any inappropriate measure of precision will invalidate data, and that is even worse than having no measure of precision. Finally, I appreciated how he gave examples of how an index could still be used as credible data – while Anderson was quick to pass judgment and condemn all use, Engerman was less concerned about the use of that practice and more concerned about using poor experimental designs as a whole. Here, I agree more with Engerman – poor experimental design appears to be the problem, not the use population indices to compute relative abundances.

The area of an animal has an enormous influence in affecting their producers contribution to their size. A portion of the animals on the

These ratios are plotted on the graph along with the line f(x)=1+52, the golden ratio, to compare them.

Recently, scientists in Norwell, Massachusetts collected a ratio of the amount of gray and brown Deer Mice out of 50 mice. The to the left below, shows the ratio of 24:26. Also, to the bottom right, a chart shows the percentage of the how much the gray and brown mice take up the population.

There are a variety of methods that can be used when trying to estimate population size. A common method used by wildlife biologists is the capture, mark, and recapture method. This method is particularly useful when trying to estimate the population size of a mobile or far-ranging species. Some

In the area of mathematics, two quantities are in golden ratio if the ratio between the two quantities is the same as the ratio of the sum of the two quantities to the sum of the larger of the two

The ratio is used to measure the performance of the portfolio since it makes it easier to compare the performance of one portfolio to another while

The relationship can be expressed in percentage , fractions and proportion of numbers. The various classifications of ratios are follows.
