2 answers
30 / 150 = 30 / 30 ∙ 5 = 1 / 5
30 / 150 = 30 / 30 ∙ 5 = 1 / 5 damaged eggs
1 - 1 / 5 = 5 / 5 - 1 / 5 = 4 / 5 good eggs
good eggs / damaged eggs = 4 / 5 / ( 1 / 5 ) = 5 ∙ 4 / 1 ∙ 5 = 4 / 1
1 - 1 / 5 = 5 / 5 - 1 / 5 = 4 / 5 good eggs
good eggs / damaged eggs = 4 / 5 / ( 1 / 5 ) = 5 ∙ 4 / 1 ∙ 5 = 4 / 1
