#=5 815/1000 +6 21/1000#

Explanation:

Decimals can be written as fractions with denominators that are powers of #10#

#5.815 +6.021#

#=5 815/1000 +6 21/1000#

We could simplify #815/1000#, but then the denominators would be different, so leave the fractions as they are.

If we add we will get:

#5 815/1000 +6 21/1000#

#=11 836/1000#

#=11 209/250#
