Question

It takes Jacob 25 minutes to line 2/3 of the flag football field. At this rate, how long will it take to line the entire field. *

Answer 1

37.5 minutes

Explanation:

We can set a ratio to model this problem

It takes Jacob 25 minutes to line 2/3 of the flag football field.

The ratio here is 25 : 2/3.

We want to figure out what x : 1 is.

25 : 2/3

x : 1

We can model this by fractions:

`(25)/((2)/(3)) = x`

When you divide by a fraction, you end up multiplying it by the reciprocal.

`25((3)/(2))=x`

`x=(75)/(2)`

`x = 37.5`

Answer 2

12.5 minutes

Explanation:

Just divide 25 by 3 to get 12.5
