Answer 1

First we should change these mixed numbers into improper fractions:

$12 \frac{4}{9}= \frac{112}{9}$

$1 \frac{7}{9}= \frac{16}{9}$

We can find the number of crates used by dividing the total amount of electrical supplies by the amount that each crate can hold:

$\frac{112}{9}$ / $\frac{16}{9}=\frac{112}{9}$ * $\frac{9}{16} = \frac{1,008}{144}=7$

So now we know that Otto used 7 crates.
