The sixth grade class has 18 boys and 24 girls. The teacher wants to divide them into groups that have the same number of boys and the same number of girls. What is the greatest possible number of the groups the teacher can make

The teacher can make 7 groups of 6 students

Step-by-step explanation:

24+18= 42. The biggest number you can use to divide and get a real number is 7.

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
