Emma has 56 37⁄40 bags of dog food to feed all of the dogs at the animal shelter. The dogs each eat 81⁄4 bags of food per week.
deff fn [24]

\text{Answer: Number of weeks }=56

Explanation:

Since we have given that

\text{Number of bags of dog food to feed all of the dogs at the animal shelter} =56\frac{37}{40}\text{Number of bags of food per week eaten by dogs }= 8\frac{1}{4}

So,

\text{Number of weeks worth of dog food Emma have } =\frac{56\frac{37}{40}}{8\frac{1}{4}}

\text{Number of weeks worth of dog food Emma have }=\frac{2240\times 4}{40\times 4}\\\text{Number of weeks worth of dog food Emma have }=\frac{2240}{40}\\\text{Number of weeks worth of dog food Emma have }=56

∴ \text{Number of weeks worth of dog food Emma have}=56
