To determine in how many pices of 2/3ft can a 9ft long ribbon be cut, you have to divide 9 by 2/3:
![9/(2)/(3)](https://img.qammunity.org/2023/formulas/mathematics/college/tt7fs5tsj70sikvftbmuswc7xaq69tk8hw.png)
To divide both fractions, first turn the 9 into a fraction by adding 1 as a denominator
![(9)/(1)/(2)/(3)](https://img.qammunity.org/2023/formulas/mathematics/college/hiwgmutzqxwbe6tk3ry2fg0rhg74terl4e.png)
Now you have to invert the fraction that is the denominator of the division
![(2)/(3)\to(3)/(2)](https://img.qammunity.org/2023/formulas/mathematics/college/n4gabh32c22kfqhjweaxmk0imx7erab8db.png)
And multiply it by the first fraction
![(9)/(1)\cdot(3)/(2)=(9\cdot3)/(1\cdot2)=(27)/(2)\cong13.5](https://img.qammunity.org/2023/formulas/mathematics/college/ayq3h1pp5ftiu5uzlmj5sp4qgt9ke0qexk.png)
She can divide the ribbon in 13 pieces of 2/3ft each
