Introduction:
The least count of a measuring instrument is the smallest value that can be measured or read from the instrument. It is determined by the smallest division on the scale of the instrument. In this case, we are given that one centimeter on a scale is divided into 20 equal divisions and we need to find the least count of the scale.
Explanation:
To find the least count, we need to determine the smallest measurable value on the scale. Since one centimeter is divided into 20 equal divisions, each division represents a fraction of 1/20th of a centimeter.
Conversion:
To convert this fraction into millimeters, we need to remember that 1 centimeter is equal to 10 millimeters. So, we can convert 1/20th of a centimeter to millimeters by multiplying it by 10.
Calculation:
1/20th of a centimeter = (1/20) * 10 mm = 0.5 mm
Conclusion:
Therefore, the least count of the scale is 0.5 mm. This means that the scale can measure or read values in increments of 0.5 mm.

1 cm = 10 mm.
10 mm ÷ 20 = 0.5 mm
