Answer
The ratio is 1:1.
The painting can have any other measurement of length and maintain the same ratio.
Work Step by Step
Comparing both values
$2 \frac{7}{12} $ to $2 \frac{7}{12} $
we easily see that the length of the longest and shortest side is the same, which is an one-to-one ratio 1:1.
The painting can have any other measurement of length and maintain the same ratio.
As example: 1 feet = 12 inches.
We compute with the converter by multiplying
$2 \frac{7}{12} \cdot 12 = 30.96$inches.
As example: 1 feet = 0.3 meters
We compute with the converter by multiplying
$2 \frac{7}{12} \cdot 0.3 = 0.775$meters.
