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]
