Answer :
Answer:
1:4
Step-by-step explanation:
Current map scale 1:12
Three times bigger would be
[tex]3\times \frac{1}{12}=\frac{1}{4}=1:4[/tex]
This would mean that 1 inch on the map would be 4 yards in the real world
Let us take example
If something measured 100 yards in the real world then in the old map it would be [tex]\frac{100}{12}[/tex]=8.33 inches in the map
Now in the new map if something measured 100 yards in the real world then in the new map it would be [tex]\frac{100}{4}[/tex]=25 inches.
So, the new scale would be 1:4, this means that 1 yard in the actual world would be 4 inches in the map.
