Question

Santa has 3/4 of a bag of grain left. His hens eat 1/6 of a bag of grain every day. How many days will he be able to feed his hens?

Answer 1

To find how many days he is able to feed his hens, divide 3/4 by 1/6.

$\frac{\frac{3}{4}bag}{\frac{1}{6}\frac{day}{day}}$

To solve it multiply the first fraction by the inverse of the second fraction.

$\begin{gathered} \frac{3}{4}bag*\frac{6}{1}\frac{day}{bag} \\ \frac{6*3}{4}days \\ \frac{18}{4}days \\ 4.5days \end{gathered}$

That means he will be able to feed his hens for 4 days.

Answer: 4 days.
