Answer: 243 people
Step-by-step explanation:
ration of 7 children to every 2 caretakers, and there are 189 children. So, since ratio of children is 7, divide 189 by 7 and get 54. Then multiply by 2 since that is the ratio for caretakers to get 54 caretakers. You can check these numbers by putting in the calculator 189/54, it simplifies to 7/2. Add 54 and 189 to get total number of people which is 243.
