Express the ratio in simplest form.

5 1/2 days to 2 1/2 weeks

A) 11 : 5
B) 5 : 2
C) 11 : 35
D) 77 : 5

2.5 weeks = 17.5 days

5.5/17.5 = ?

Divide both top and bottom by .5.

5 days to 1 week

To express the ratio in simplest form, we need to convert both the days and weeks into a common unit.

First, let's convert 5 1/2 days to weeks. Since there are 7 days in a week, we divide 5 1/2 by 7 to find the equivalent in weeks:
5 1/2 days = (5 + 1/2) days = 5.5 days
5.5 days ÷ 7 days/week = 0.7857 weeks (rounded to four decimal places)

Next, let's convert 2 1/2 weeks to days. Again, we use the fact that there are 7 days in a week:
2 1/2 weeks = (2 + 1/2) weeks = 2.5 weeks
2.5 weeks × 7 days/week = 17.5 days

Now we have the equivalence:
5 1/2 days = 0.7857 weeks
2 1/2 weeks = 17.5 days

To express the ratio, we divide the number of days by the number of weeks:
0.7857/17.5 ≈ 0.0448

To simplify this ratio, we multiply both sides by a common factor to get whole numbers. In this case, we can multiply by 1000 to eliminate the decimal:
0.0448 × 1000 ≈ 44.8

So the simplified ratio is approximately 44.8:1.
