Answer: 30 kids.
Step-by-step explanation:
Since Mrs. Cunningham's ratio from boys to girls is 2:3 ( with girls being 3) you just need to multiply 6 to 3 to get 18. But you also need to multiply 6 and 2 then add both numbers together, which gets you to 12.
Answer:
30
Step-by-step explanation:
because if ratio 3 is girls and there are 18 of them if you divide that by 3 you get 6 than multiply 6 time the ratio of boys 2 to get 12 then add 18+12
