Question

It takes 3/5 feet of ribbon to make a pin. You have 9 feet of ribbon. How many pins can you make?

Answer 1

You can divide $9$ by $\frac{3}{5}$ to find the amount of pins, (let's call this number $x$), you can make with $9 ft$ of ribbon.

$x=9 \div \frac{3}{5} \\ \\ x= \frac{9}{1} \div \frac{3}{5} \\ \\ x= \frac{9}{1} \times \frac{5}{3} \\ \\ x= \frac{9 \times 5}{1 \times 3} \\ \\ x= \frac{45}{3} \\ \\ x=15$

So, $15$ pins can be made.
