Question

How many groups of 1/2 days are in 1 week? Use the tape diagram below to answer the question?A:3.5B:5C:7D:14

Answer 1

Two halves of one day together are equivalent to one day, then we can express the ratio of half days to a day like this:

`\frac{\text{halfs of a day}}{day}=(2)/(1)`

Then, to find how many groups of half-days are in seven days (one week) we just have to multiply the number of days (7) by the ratio expressed above, like this:

`7*(2)/(1)=7*2=14`

Then, there are 14 groups of 1/2 days in a week
