Answer 1

Explanation:

Add 1/2+1/2=1/1 or 1

If she needs 1/8 runners

Half of 1/8 is 1/4 or 1x4=4

Or 2x2=4

Answer 2

16 runner

Explanation:

It is given that,

Each group will need to run a race that is 1/2 of a mile long. Each runner has to run 1/8 of a mile in the race.

Let there are x no of runners. ATQ,

`(1)/(8)x=(1)/(2)\\\\x=((1/2))/((1/8))\\\\x=16`

So, there are 16 runner that are needed for each relay race group.
