Sophia went to an amusement park. She went on 18 rids in all. 7 of the rides were roller coasters. How many of the rides Sophia went on were not roller coasters?

Subtract

18-7=11

Right.

thank you

You're welcome.

To find the number of rides Sophia went on that were not roller coasters, we can subtract the number of roller coaster rides from the total number of rides.

Given that Sophia went on a total of 18 rides and 7 of them were roller coasters, we can calculate the number of rides that were not roller coasters:

Number of rides that were not roller coasters = Total number of rides - Number of roller coaster rides

Number of rides that were not roller coasters = 18 - 7

Number of rides that were not roller coasters = 11

Therefore, Sophia went on 11 rides that were not roller coasters.
