Step-by-step explanation:

Jenna ran 2 7/8 kilometers each day for a week. How far did she run in all?

We can simply use proportion to solve this;

But we need to know that 7 days = 1 week

If Jenna ran 2  kilometers each day, we are now going to find how many kilometers she run in a week(7 days)

Let x be the total distance she ran in a week

2  kilometers  =  1 day

   x                      = 7 day

Cross-multiply

x  = 2   ×  7

   =   ×   7

    =

    =20  kilometers

Therefore Jenna ran 20  kilometers in a week.
