I neef help with this is due today

Answer:
[tex]\frac{1}{16}[/tex] mile
Step-by-step explanation:
First we need to figure out what she has done:
3/4 + 1/8 -> 6/8 + 1/8 = 7/8
Then what she has left:
15/16 - 7/8 -> 15/16 - 14/16 = 1/16
So she needs to walk the bike 1/16 of a mile :D
Hope this helps, good luck! :)
