For every 3 zippers there are 2 houses. If there are 12 zippers,
how many houses would there be?

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%!!!
