How much milk is used for each slice of bread? using comparison statement

You need to write the milk and the bread number or some things we know I not trying to be mean. Do you mean how much I used for each slice of bread is I filled my milk 1/2 full and used 1/4 of the bread because my bread is the long kinds and each slice I just put it in my milk and spoon it up with my spoon and that all some times I don't know how much I used because I need to hurry.
