Answer 1

$2\frac{3}{10} +2\frac{3}{10} =\frac{(2\times10)+3}{10}+\frac{(2\times10)+3}{10} =\frac{20+3}{10}+\frac{20+3}{10}\\\\=\frac{23}{10} +\frac{23}{10} =\frac{23+23}{10} =\frac{46}{10} =4\frac{6}{10} =\boxed{\bf{4\frac{3}{5}}}$

Marissa rode 4 3/5 miles in all.

Answer 2

Well since she rode 2 3/10  to the park and back the  problem would be 2 3/10 +2 3/10 which would equal 4 6/10 
hope that helps.
