Which one of the selections shown is NOT a standard metric scale

Which one of the selections shown is NOT a standard metric scale

1:10

1:50

1:45

1:25

Answer 1

Out of the scales provided, 1:45 is NOT a standard metric scale; the rest, such as 1:10, 1:50, and 1:25, are standard metric scales.

Therefore, the correct answer is: option '1:45'.

Step-by-step explanation:

A metric scale measures quantitative characteristics or variables. The term metric scale summarizes interval scales, ratio scales, and absolute scales. Quantitative numerical values allow for most statistical calculations and comparisons.

The standard metric scales are often in the form of 1:10, 1:20, 1:25, 1:50, 1:100, etc., as they reflect a clear fractional relationship within the metric system where measurements are scaled down in a consistent and logical manner.

In the list provided, the scale of 1:45 is not a commonly used standard metric scale. The other scales mentioned, 1:10, 1:50, and 1:25, are standard metric scales commonly used in various applications such as architectural and engineering drawings, models, and maps.
