Answer:

B

Step-by-step explanation:

Fraction subtraction:

 [tex]\sf 6 \dfrac{3}{5}-(-2\dfrac{1}{5})=6\dfrac{3}{5}+2\dfrac{1}{5}[/tex]

Convert mixed fraction to improper fraction,

                    [tex]\sf = \dfrac{33}{5}+\dfrac{11}{5}[/tex]

Now, add.

                  [tex]\sf = \dfrac{33+11}{5}\\\\=\dfrac{44}{5}[/tex]

Covert improper fraction to mixed fraction.

                  [tex]\sf = 8\dfrac{4}{5}[/tex]
