If a hen lays 4 eggs in 5 days, at that same rate, she'd take 15 days to lay a dozen eggs. Same answer for 8 hens: 15 days. Note that the trick here is that the number of hens is irrelevent; they're not laying the eggs together.
3hens must lay 3eggs in 1.5 days
because doubling the hens must double the eggs in the same time
so by the same logic
1hen must lay 1egg in 1.5 days
so
10hens must lay 10eggs in 1.5 days
but if you double the time with the same number of hens then you double the eggs
so
10hens must lay 20eggs in 3 days
and
10hens must lay 40eggs in 6 days
and
10hens must lay 60eggs in 9 days
to get 1 day
consider that
10hens must lay 20eggs in 3 days
but in 1 day you will get 1/3 of the eggs
so
10hens must lay 6 and 2/3 eggs in 1 day
so adding
10hens must lay 66 + 2/3 eggs in 10 days
First, use the former scenario determine that rate of eggs laid per chicken per day, then apply that rate to the latter scenario.
So in this case, do your own homework.
one quarter of a dozen eggs is three eggs.
One-quarter of a dozen eggs is three eggs.

Two-thirds
Eight dozen eggs is eight sets of twelve eggs each. Each dozen costs $2.50 So you have: $2.50 + $2.50 + $2.50 + $2.50 + $2.50 + $2.50 + $2.50 + $2.50 which is equal to 8 x $2.50, or $20
36 eggs.
If you mean three eggs of a dozen then it is 3/12 or 1/4 in its simplest form
Two-thirds
a dozen eggs
Each dozen has 12 eggs. 12 X 3 = 36, then add the half dozen (6) to equal 39
A dozen eggs cost approximately $1.87 in 2005.
A dozen means twelve and so a dozen eggs is twelve eggs. Usually eggs are sold in cartons and these contain a specific number which will be either a half-dozen (which is six eggs), a dozen (that is, twelve eggs), or the number can be specified, say nine eggs, or maybe even fifteen or eighteen eggs. If you want a greater quantity of eggs you might buy a tray, which will be thirty eggs. For some reason, eggs are usually sold in multiples of three.
