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
Graphed it
If you need to do it manualy, consider using a table of values
The answer is either c or d. I would go with answer c though. sorry if it is wrong
Divide 4 by 1/10.
So, 4 ÷ 1/10 becomes 4 x 10/1.
We know that 4 x 10/1 = 40/1 = 40.
