Esteban is making turtle brownies the recipe calls for 3/4 bag or caramel squares one bag has 24 caramel squares how many caramel squares should he use for one batch ?

So basically the question is asking, what is 3/4 of 24.  

You have two options:

You can covert 3/4 to a decimal (which is .75) and multiply 24 X .75

or multiply 3/4 X 24.  Remember you can write 24 as 24/1.  

When multiplying fractions multiply the top numbers together, then multiply the bottom numbers together.  so 3/4 X 24/1 = 72/4.

Now we simply: 72/4 = 18.

He should use 18 caramel squares for one batch.

The correct graph is the second one, with the points being at (-6,0), (2,0) and reaching down to (-2,-8)
