Answer:
9
Explanation:
We can make an equation out of this
So if he has 27 blankets, and 18 flashlights, he will need to divide evenly amongst the kits.
The equation would be 
z=x+y, where x is the amount of blankets, and y is the amount of flashlights. 
to find this, we need to find what 27 is divisible by, and what 18 is divisible by. 
27 - 27, 9 , 3, 1
18 - 18, 9, 6, 2, 3, 1
Now, 18 and 27 are both divisible by 9
18/9=2
27/9=3
So we can make a total of 9 emergency kits, with each kit having 3 blankets and 2 flashlights
Hope this helps!!^^
