The task asks to express the fraction 18/100 as a decimal, i.e., to convert the ratio 18 divided by 100 into decimal form.

Option a. 0.018 — This value would correspond to dividing 18 by 1000, not 100, so it is too small by a factor of 10.

Option b. other — This is a placeholder choice and does not provide a numeric decimal; it cannot be correct unless the value matches the conversion, which it does not specify.

Option c. 1.08 — This value would come from dividing 108 by 100, or from misplacing the decimal point; it represents a number greater than 1, which is inconsistent with dividing 18 by 100.

Option d. 1.8 — This is even larger and would result from dividing 180 by 100, not 18 by 100; it is not the correct decimal for 18/100.

Option e. 0.18 — This is the correct decimal form for 18/100 because moving the decimal two places to the left (since you divide by 100) converts 18 to 0.18. This matches the standard decimal conversion rule for fractions with a denominator of 100.

In summary, converting a fraction with denominator 100 to a decimal involves shifting the decimal point two places to the left. The only option that aligns with this rule for 18/100 is 0.18.
