If a map at a scale of 1:50,000 is reduced by half, what is the new scale of the map?
1:100,000
1:25,000
1:200,000
1:250,000
คำอธิบาย
New scale of the map: 1:25,000 > 1:50,000 reduced by half becomes 1:25,000 is incorrect, 1:100000 would be double the scale, half would be 1:100,000. So 1:50000 reduced by half is 1:100,000
