Answer:
8 houses
Step-by-step explanation:
Since there is 3 zippers for every 2 houses , you can put that into ratio form, for example :
3 : 2
Now that there is 12 ZIPPERS , we want to figure out how many houses , for example:
12: ?
First what you want to do is figure out how we ended out with the number , so we will take 3 zippers we started with and the 12 zippers we have now. We are going to divide the 3 from 12 leaving us with 4 as our quotient .
12÷3=4
Now that we have 4 groups of houses we can multiply 4 x 2 equaling us with , yes you guessed it 8 .
In ratio form the answer is this :
3 : 2 = 12 : 8
I hope you get a 100%!!!
