Question

BlackTom AI · Accepted Answer

To tackle the problem, begin by identifying what the expression is asking you to convert. The given options suggest we are converting a fraction to a decimal.
Option a: 0.05. This corresponds to the fraction 1/20, not 1/40, so this is not the correct decimal representative of 1/40.
Option b: 0.25. This equals 1/4, which is much larger than 1/40, so this option misrepresents the fraction in question.
Option c: 0.025. Since 1/40 means one part out of forty, dividing 1 by 40 yields 0.025. This aligns with the standard decimal conversion of a simple fraction with a denominator of 40.
Option d: Other. This would be chosen if none of the provided decimals matched the conversion, but one option does match exactly, so this choice is not appropriate.
Option e: 1.40. This is clearly far from the value of 1/40, which would be a fraction of a unit rather than more than one unit, so this is incorrect.
In summary, the only option that faithfully represents the decimal form of 1/40 is 0.025, since 1 divided by 40 equals 0.025. The other choices correspond to different fractions (or misinterpretations) and do not equal 1/40.
