Then you have a problem.
You simply get them under fraction form :
4/10 + 2351/1000
= 400/1000 + 2351/1000
= 2751/1000
Being able to manipulate fractions is kinda important. And although once you reach higher studying levels (engineering for instance) you have calculators that will easily solve that, it's still important to teach this kind of math to kids, and more importantly you should be able to figure this out if you're in engineering.

Those are repeating decimals. It wouldn't be 4/10, it should be 4/9. The other one, I can't figure out.
EDIT: The other is 388/165. Add em together, and the answer is 1384/495

Oh, mb, had no idea what that bar was. In France we never saw that notation, if we have repeating numbers they are always written in their exact fraction form since that's the only exact representation.

if you are on the job and your calc breaks. Or if you are trying to build something in a place with nothing more than a ruler but you need to decipher something round.

Generally you do most math and designs on a computer that will account for this. You mostly need to know higher forms of math and generally you have plenty of calculators on hand.

You're chasing the least significant digit. The best accuracy available in the equation is the 'bar 4'. This means the sum is 2.7xx, where the 'xx' (coz I can't find a vinculum on my keyboard) here shows the significant digits stop at the seven, as that's the last significant digit. So the answer is 27/10.
