The other guys probably right can u make me as brainliest?
First off, if it's mixed, you'd want to convert it to "improper" first, and then do the division... say hmm - 3 and 1/7

the line over the decimal part is because is a "recurrent decimal", or repeating one.
2x -4y=20
-4y=-2x+20
Y= 1/2x - 5 that’s the answer
So the scale is 3/4 cm for every 6 meters
So if you have 8 cm, we want to find the dimension of the actual wall
convert cm to meters
0.75 cm = 0.0075 meters
8 cm = 0.08 meters

Cross Multiply
0.0075x = 0.48
x = 64 meters
