Which one of the following is the largest scale?a)1 : 500b)1 : 1000c)1...
Upon solving,
1/500 = 0.002
1/1000 = 0.001
1/2500 = 0.0004
1/50000 = 0.00002
Largest is 0.002 i.e. 1/500

Scale in Civil Engineering
Scale in civil engineering refers to the ratio of the dimensions of the object being represented on a map or drawing, to the actual dimensions of the object in the real world. It is usually expressed as a fraction or ratio, such as 1:500, 1:1000, 1:2500, 1:50000, etc. The larger the denominator of the ratio, the smaller the scale, and vice versa.
Determining the Largest Scale
To determine the largest scale, we need to look at the denominator of the ratio. The denominator represents the actual size of the object in the real world, while the numerator represents the size of the object on the map or drawing.
Comparing the options given:
a) 1:500 - Here, the denominator is 500, which means that the actual size of the object is 500 times larger than its size on the map. This is the smallest denominator among the given options.
b) 1:1000 - Here, the denominator is 1000, which means that the actual size of the object is 1000 times larger than its size on the map.
c) 1:2500 - Here, the denominator is 2500, which means that the actual size of the object is 2500 times larger than its size on the map.
d) 1:50000 - Here, the denominator is 50000, which means that the actual size of the object is 50000 times larger than its size on the map. This is the largest denominator among the given options.
Therefore, the largest scale is 1:500 (option a).
