Rewriting Ratios Worksheets
How to Write A Ratio Based on the Number of Objects in a Group Determining the ratio of a single object out of an entire group can be difficult at first. For example, a group consists of objects A, B, C, and D, and the total number of objects in that group is 100. At first, it can be a bit difficult to determine the ratio of object A out of the entire population of 100. Might as well you need to calculate the number of object A in that group manually. But after you are done with the manual calculation of the objects in the entire group, the calculation of ratio is pretty simple. The ratio of a certain object in the entire population of a group of certain objects is simple to calculate. After you have counted the number of object A, you can simply divide it by the total number of objects in the population. The answer you get will be the ratio of object A in the entire population.
