Answer:
- the title says "word problem". The GCF is the solution.
- 4 arrangements
Explanation:
The number of arrangements is the largest factor that can be found for the numbers 8, 12, 20. That number would be the "greatest common factor" or GCF. You know it's a GCF word problem because it's a word problem (the problem says so) that has a GCF as its solution.
__
GCF(8, 12, 20) = 4
Using Euclid's algorithm we can find the GCF as 12 mod 8 = 4, which is a divisor of all the numbers.
Ms. Johnson can make 4 arrangements with the balloons she has.
Each of the 4 arrangements will have 40/4 = 10 balloons: 2 blue, 3 white, 5 yellow.
