Carly, Brittany, and Lauren streamed one-fourth of an eight-episode documentary. If 70 minutes of the documentary have been watched, how many minutes are in the documentary?

We can start by using ratios to solve this problem.

If one-fourth of the documentary is 2 episodes (since 8 divided by 4 is 2), then each episode is 1/2 of the one-fourth share.

So, 1/2 of the one-fourth share is equal to 1/8 of the documentary.

Therefore, if 70 minutes have been watched, this is 1/8 of the total minutes in the documentary.

We can set up a proportion:

1/8 = 70/x

where x is the total number of minutes in the documentary.

Cross-multiplying, we get:

8*70 = x
560 = x

Therefore, there are 560 minutes in the entire documentary.

that's not correct
