Answer:
88%
Step-by-step explanation:
3 / 25 of all adults visited the zoo
Since we dealing with fractions;
Adults that visited the zoo + Adults that did not visit the zoo = 1
Adults that did not visit the zoo = 1 - 3 / 25
Adults that did not visit the zoo = 22 / 25
What is the percent?
Adults that did not visit the zoo = 22 / 25 * 100%
Adults that did not visit the zoo = 0.88 * 100% = 88%
