Answer:
3 carrots, 4 crackers, and 6 grapes.
Step-by-step explanation:
The greatest common factor of 9, 12, and 18 is 3, so we know that we can make at most 3 identical lunchboxes. Now we have to divide each number by 3 to figure out how much of each item is in each lunchbox. 9/3=3, 12/3=4, and 18/3=6 so there will be 3 carrots, 4 crackers, and 6 grapes in each lunchbox.

Answer:
630
Step-by-step explanation:
The ratio of students that would like to try or already have tried snorkeling is 7/9.
The ratio of all students is an unknown amount out of 810 total students; this gives us x/810.
This gives us the proportion:
7/9 = x/810
Cross multiplying,
7*810 = 9*x
5670 = 9x
Divide both sides by 9:
5670/9 = 9x/9
630 = x
