Ok so lets start with the 5 dozen there are 12 eggs in one dozen so we do 12*5 which gives us 60 and then we figure out what 3/4 of 12 is that sounds confusing the way i typed it. an example is make four piles each evenly numbered so four piles of three so take three of those piles which gives you the number nine so 60 + 9 gives you 69 so Jesse has 69 eggs.

You are estimating each into whole numbers. They are already whole numbers, and so just subtract.
428,734 - 175,842 = 252892
252,892 is your answer
hope this helps
