10. On one night, a group of 9 rats carried away 45 kg of food. What is the reduced ratio of rats to food weight

GenaCL600 [577]

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 = $\frac{\text{Number of rats}}{\text{Weight of food carried by the rats}}$

= $\frac{9}{45}$

= $\frac{1\times 9}{5\times 9}$

= $\frac{1}{5}$

Therefore, Number of rats : Food weight = 1 : 5
