The math concept here is what we call 𝐞𝐪𝐮𝐢𝐯𝐚𝐥𝐞𝐧𝐭 𝐟𝐫𝐚𝐜𝐭𝐢𝐨𝐧𝐬. So if you had a denominator of 5 that means it's broken down into 5 total pieces. But what if it were broken into 25 pieces. If you had 3 of the 5 pieces originally, how many of the 25 pieces would you need to equal those 3 out of 5 you originally had? So 3/5 = how many out of 25? That's the basic concept here!
So what you would do is look at each of those pictures and count how many pieces they are each broken into. That number would be your denominator! To get your numerator, you'd divide this by how many it was originally broken into. In my example, it's 2. But with yours, it would be 4.
Here is a illustration I put together to show you how students are often taught the concept. So the box on top is where we started. Then we subdivided this box into a different number of pieces. The bracket in between helps show you how many pieces in the newly subdivided one equate to, meaning equal, the original.Source(s): I've taught math and many other subjects. And have helped lots of students out with problems. Providing them with helpful guidance so they can better understand and figure things out.

so you are supposed to represent 1/4 in all models
so count the number of square/slices/or whatever in the picture
then divide that number by 4
then, color in number of square/slices/or whatever / 4
so 1st one has 8 squares
divide by 4 8/4 = 2
so color in 2 squares
2/8 = 1/4
so I don't know if they want 2/8 or 1/4 in the fraction.
the 2nd one has 12 squares
12/4 = 3
so color in 3 squares
3/12 = 1/4
(again they want 3/12 or 1/4 in fraction)
the 3rd one
color in 4 slices
4/16 = 1/4
(again they want either 4/16 or 1/4 in the fraction)
