Question

Katia makes crafts using glass jars. She can buy a package of $12$ jars for $\$9$. How many jars can Katia buy with $\$45$?

Answer 1

Finding the numbers of glass jars:

Step 1: Find the price of $1$ glass jar.

The price of a package of $12$ jars is $\$9$.

So, the price of $1$ glass jar will be $=\frac{9}{12}$

$=\frac{3}{4}\text{dollars}$

Step 2: Calculate the number of glass jars.

The price of $1$ glass jar is $\$\frac{3}{4}$.

So, the number of glass jars that can be bought with $\$45$$=45÷\frac{3}{4}$

$$\begin{gathered} =45\times \frac{4}{3} \\ =60 \end{gathered}$$

Therefore, Katia can buy $60$ glass jars with $\$45$.
