HHT Task 1 Part A In a classroom where an A is based on having 90% or higher of 334 points, rounding and truncation can be the difference between a whole letter grade. Student 1 has 299 points out 334 point in the class. So to figure out what is percentage is you simply put 334/100= 299/x which breaks down to 334x=29900 so than divide 334 into 29900 and you get 89.52%. Now if we round up the Student 1 grade would be 90% which is an A. This is because the 5 in the .52 digit means we would round the whole number up by one whole digit. So it would go from 89 to 90. Now if the teacher were to be truncating the grade and not rounding it could change the student’s grade by up to one whole grade level. Student 1 89.52 when truncated would make the grade by 89% flat. So that means the students grade would be a B. The reason the teacher would want to truncate the grade is it would make it easier when doing grading for 20+ students taking the additional time to round would make the teacher have to spend more time figuring out the grade for the students than if he were to simply truncate the grade. By truncating he just takes the whole number before the decimal in the students grade and makes that their final grade for the class. So if it was 89.6 the final grade would be 89% same as if it was 89.1 than the final grade would be 89%. A taxpayer if given the choice would always choose to have their taxes truncated and not rounded. This is, because by truncating they will have to pay fewer taxes than if there government were to round. So let’s say there taxes is 27.5, 27.6, 27.7, 27.8, and 27.9 when rounding this would increase the taxpayer taxes from 27% to 28% which could equal a few hundred or thousands of more dollars. This is due to the rules of rounding which dictate that anything above 5 directly after a decimal point would increase the whole number by a value of 1.
