Answer:
3 inches
Step-by-step explanation:
We can use proportions to solve. Put the map on top and the real life size on bottom.
1 inch x inches
------------- = -------------
4 ft 12 ft
Using cross products
1 * 12 = 4 * x
Divide each side by 4
12/4 = 4x/4
3 =x
3 inches
62.4% I think Because you move the decimal over 2 places.
0.3x = 48
So x is 48/0.3
Therefore, 0.5 times 48/0.3 is the answer
