The intermediate answers from some calculations based on whole number scores are X= 4.3467892 and Y= 3.3333. For the next step, after rounding, what values of X and Y do we use?
rounding to what?
nearest whole number
(4,3)
to one decimal place?
( 4.3 , 3.3 )
to two places
(4.35 , 3.33)
etc etc etc
To determine the values of X and Y after rounding, we need to decide on the desired level of precision. Rounding allows us to convert the decimal values into a more manageable form.
Let's start with X = 4.3467892:
If we want X to be rounded to the nearest whole number, we look at the digit immediately to the right of the decimal point. In this case, it is 3. Since 3 is less than 5, we round down, and X becomes 4.
Moving on to Y = 3.3333:
If we want Y to be rounded to the nearest whole number, again, we look at the digit immediately to the right of the decimal point. Here, it is 3. Since 3 is also less than 5, we round down, and Y becomes 3.
After rounding, the values of X and Y are X = 4 and Y = 3.
