- All numbers are rational, meaning they can be written as fractions and have either terminating or repeating decimals.
- We simplified each fraction to lowest terms first (by dividing numerator and denominator by their GCF), then converted to decimals via division.
- All results are terminating decimals, which confirms they are rational.
