Numerical Methods: Calculate 4/5 + 1/3

AI Thread Summary
The discussion focuses on calculating the sum of 4/5 and 1/3 using three-digit arithmetic. The exact sum, 4/5 + 1/3, simplifies to 17/15, while the chopped decimal values yield 1.13. The relative error is calculated as the absolute difference between the exact value and the chopped result, divided by the exact value, resulting in approximately 0.0033. The relative error is expressed in three significant digits as 3.33 x 10^-3. Participants are seeking confirmation on the accuracy of these calculations and the relative error.

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 \frac{\frac{17}{15} - 1.13}{\frac{17}{15}} = 0.0033
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!

AM i right in any of these by the way?

Please help/advise/suggest

thank you for your time!
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
