Answer:
Number of rats : Food weight = 1 : 5
Step-by-step explanation:
Number of rats in the group = 9
Weight of food carried away by them = 45 kg
Ratio of the number of rats and food weight = [tex]\frac{\text{Number of rats}}{\text{Weight of food carried by the rats}}[/tex]
= [tex]\frac{9}{45}[/tex]
= [tex]\frac{1\times 9}{5\times 9}[/tex]
= [tex]\frac{1}{5}[/tex]
Therefore, Number of rats : Food weight = 1 : 5
