Numerical Methods: Calculate 4/5 + 1/3

Click For Summary
SUMMARY

The discussion focuses on calculating the sum of 4/5 and 1/3 using three-digit arithmetic and determining the relative error of the result. The correct computation yields 4/5 + 1/3 = 17/15. The values are chopped to 0.800 and 0.333, resulting in a sum of 1.13. The relative error is calculated as |(17/15 - 1.13) / (17/15)|, which equals 0.0033, expressed in scientific notation as 3.33 x 10^-3.

PREREQUISITES
  • Understanding of three-digit arithmetic
  • Knowledge of relative error calculation
  • Familiarity with fractions and their decimal equivalents
  • Basic concepts of significant figures

Not a hard question really..

Using 3 - digit arithmetic calculcate 4/5 + 1/3 and compute the relative error

4/5 + 1/3 = 17/15
chopping 4/5 = 0.800 and 1/3 = 0.333
0.800 + 0.333 = 1.133 (chop) 1.13
im assuming that after this point there is no chopping
relative error aboslute value of [tex]\frac{\frac{17}{15} - 1.13}{\frac{17}{15}} = 0.0033[/tex]
and the rleaitve error would be given in 3 siginificant digits?
sp 3.33 x 10^-3 is the relative error?

please tell me if i am right or wrong?

Your help is grealty appreciated!
