Billions and billions of broken eggs



In the U.S. in 1998, hens produced 6,657,000,000 dozen eggs - that's 6.657 billion dozen! (Multiply by 12 to find out how many individual eggs that is.) After these eggs were laid, about two-thirds (2/3) were sold in the shell and one third (1/3) of them were broken - not by accident, but on purpose. Why? Because after the eggs are broken out of their shells, they can be made into liquid, frozen, dried and specialty egg products.

Some of these egg products are used by food manufacturers to make other foods - mayonnaise, ice cream and cake mixes, for example. Some are used by restaurants and other foodservice outlets for cooking and baking - maybe even your school cafeteria.

It would take a very long time for human hands to break all these eggs. Instead, special machines break the shell and sometimes separate the yolk and white, too. When the eggs are separated, the yolk falls into a special cup and the white slips into another container. These machines work very, very fast. One machine can break 108,000 eggs an hour.

Can you figure out how many eggs the machine can break each minute? Each second?

To answer the questions, you need to do these math problems:

108,000 (eggs broken in one hour) divided by 60 (minutes in one hour) = X (eggs broken in one minute)

X (eggs broken in one minute) divided by 60 (seconds in one minute) = Y (eggs broken in one second)

The answers to the math problems are:

X = 1,800 eggs broken in one minute
Y = 30 eggs broken in one second
