DANA IS PLANNING TO RUN 1 TENTH OF A MILE EVERY DAY FOR 8 DAYS,WHAT PART OF A MILE WILL SHE HAVE RUN AT THE END OF THE EIGHTH DAY?

8 * (1/10) = 8/10 = 4/5 mile

To find out what part of a mile Dana will have run at the end of the eighth day, we need to multiply her daily distance by the number of days.

Dana plans to run 1 tenth of a mile, which can be written as 1/10 mile, every day for 8 days.

So, the calculation would be:
1/10 mile * 8 days = 8/10 mile

Simplifying the fraction 8/10 gives us:
8/10 = 4/5

Therefore, at the end of the eighth day, Dana will have run 4/5 of a mile.
