So,
The area of art can be found multiplying:
8in * 10in = 80in²
And, the area of the frame, can be also found multiplying the dimentions:
4in * 6in = 24in².
If we divide, we'll obtain a ratio between the area of the frame and the area of the art as follows:
![(24)/(80)=0.3](https://img.qammunity.org/2023/formulas/mathematics/college/i682nyjwsu71p9af6a38t7n9kbssedw2qw.png)
And, 0.3*100% = 30%.
So,30 percent of the original sketch was still able to be included in the frame.
