Ursula has 1/2 cup of butter. She uses 1/4 to make a bath of brownies. Part A: how many batches of brownies can Ursula make with 1/2 cup of butter?

Part B:on your paper, draw a fraction model that shows the total number of batches of brownies that Ursula can make with 1/2 cup of butter. Make sure to label the model. Below, explain your model in detail to describe how this model visually shows the solution for part A.
(For part B just discribe what the model should look like so I can put it down, and the labels too please!)
