Answer:
14 children are wearing a red shirt in the park.
Explanation:
The fraction 7/8 is 7 out of 8 but your total kids is 16 so we can go ahead and multiply by 2.
(7*2)/(8*2)
14/16
So now it's 14 out of 16 kids which is the total you have.
Conclusion: 14 Children are wearing a red shirt in the park.
