Answer:
Therefore Jenna ran 20 [tex]\frac{1}{8}[/tex] kilometers in a week.
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 [tex]\frac{7}{8}[/tex] 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 [tex]\frac{7}{8}[/tex] kilometers = 1 day
x = 7 day
Cross-multiply
x = 2 [tex]\frac{7}{8}[/tex] × 7
= [tex]\frac{23}{8}[/tex] × 7
=[tex]\frac{161}{8}[/tex]
=20 [tex]\frac{1}{8}[/tex] kilometers
Therefore Jenna ran 20 [tex]\frac{1}{8}[/tex] kilometers in a week.
