Marissa rode her bike to the park and back home. She lives 2 3/10 miles from the park. How many miles did Marissa ride her bike in all.

Give u 20 points

Answer 1

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.

Answer 2

`2(3)/(10) +2(3)/(10) =((2*10)+3)/(10)+((2*10)+3)/(10) =(20+3)/(10)+(20+3)/(10)\\\\=(23)/(10) +(23)/(10) =(23+23)/(10) =(46)/(10) =4(6)/(10) =\boxed{\bf{4(3)/(5)}}`

Marissa rode 4 3/5 miles in all.
