Answer: 2:13
Step-by-step explanation:
[tex]hens \: 56 \times \frac{1}{1 + 7} = 7[/tex]
[tex]chicks \: 56 \times \frac{7}{1 \times 7} = 49[/tex]
[tex]hens=7-1=6[/tex]
[tex]
chicks=49-10=39[/tex]
[tex]
ratio: 6:39= \frac{6}{39} = \frac{2}{13} [/tex]
[tex] \frac{6}{39} (divide \: both \: sides \: by \: 3)[/tex]

2:13
