$2\frac{1}{4}$ inches.

Step-by-step explanation:

Please find the attached file for the line plot.

We are asked to find the total length of 3/4 inch buttons, if Kara lines up all.

We can see from our given line plot that there are 3 buttons having 3/4 inch length.

To find the total length of 3/4 inch buttons, we will multiply 3 by length of one button that is 3/4 as shown below:

$\text{Total length of }\frac{3}{4}\text{ inch buttons}=3\times \frac{3}{4}$

$\text{Total length of }\frac{3}{4}\text{ inch buttons}=\frac{3\times 3}{4}$

$\text{Total length of }\frac{3}{4}\text{ inch buttons}=\frac{9}{4}$

Convert to mixed fraction:

$\text{Total length of }\frac{3}{4}\text{ inch buttons}=\frac{4\times 2+1}{4}$

$\text{Total length of }\frac{3}{4}\text{ inch buttons}=2\frac{1}{4}$

Therefore, the total length will be $2\frac{1}{4}$ inches, if Kara lines up all the 3/4-inch buttons.
