Question

A farmer examines a sample of 25 cartons of eggs and finds that 3 contain cracked eggs. What is the best prediction of the number of cartons with cracked eggs in a delivery with 500 cartons.

Answer 1

3 cracked eggs per 25 eggs
3/25
so divide 500/25
you will get 20
multiply 3/25 both top and bottom by 20
you will get 60/500 or 3/5

Answer 2

This means 60 eggs out of the 500 will be cracked:) hope this helps!

Answer 3

that is a good explanation
for a quick computation you can write
\[\frac{3}{25}=\frac{x}{500}\iff x=\frac{500\times 3}{25}\] and compute that number
