Martika surfs with her friends at Virginia Beach. Her friend, Mark, caught 8 waves out of 20 possible waves to ride in to shore. They plan to stay out in the water for 50 more waves. How many of the 50 waves do you predict Mark will catch?

20 waves

Step-by-step explanation:

Out of 50 waves, Mark will catch 20 waves. To find this, first, you have to put it into a ratio.

8        x

---  =  

20      50

To solve this, you need to multiply 8 x 50, which is 400. Next you need to divide 400 by 20, which is 20 waves.

This means x = 20 waves.
