Answer 1

50 Swimmers

Explanation:

If 4/10 swimmers are stingrays, that means that roughly 40% of the swimmers are stingrays. If there are 20 Stingrays and that is 40% of 100% swimmers it means that stingrays make up 2/5 of the swim team members. You can use this equation to cross multiply:

20/x = 40/100

20/x = 4/10

20/x = 2/5

x = 50.

This shows that there are 50 people on the team.
