Answer:
The length of each paper strip is 0.25 ft.
Explanation:
It is given that Jonathon has paper strips and the length of all strips are equal.
He use 12 paper strips to make a line of paper strip and the length of the line is 3 feet.
Let the length of each paper strip be x.
![12x=3](https://img.qammunity.org/2020/formulas/mathematics/middle-school/e1f1cmac4wzwk7pzd0cm89k1mc7pcwfv3p.png)
Divide both sides by 12.
![x=(3)/(12)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/fz1j0ojnc4w6l823woazno44i4cu9ws37k.png)
![x=0.25](https://img.qammunity.org/2020/formulas/mathematics/middle-school/kxj3y5q7vad6qfm5jmywdztpy3j5ht8u82.png)
Therefore the length of each paper strip is 0.25 ft.
