Original question and givens

Ordered representations=[1/1, 26/-2, 14/29, -15/-31] all have nonzero denominators. Give (integer-membership Yes/No list, integer values, reduced noninteger values), preserving original order within groups.

  • G001 — Ordered representations=[1/1, 26/-2, 14/29, -15/-31] all have nonzero denominators. Give (integer-membership Yes/No list, integer values, reduced noninteger values), preserving original order within groups.

Definition and scope

Use the original question domain, assumptions and cited MKO definitions. This item has second-context mathematical and bilingual review, with the model, answer and every arithmetic step independently recomputed from the original parameters; the source question remains a candidate.

Step-by-step derivation

S001 · implies

Before

declared exact integer or rational-representation protocol

After

retain signs,ordered operands and original index order

Conditions: none

Check these finite data with exact integer arithmetic,without floating approximations or a claim to prove all integer-ring axioms.

Step identifiers and dependencies

Rule: integer_arithmetic_scope · Uses: G001

S002 · implies

Before

position=0;raw fraction=[1, 1]

After

normalized=1/1;integer=Yes

Conditions: none

A nonzero negative denominator is valid.Normalize to a reduced value with positive denominator;denominator1 means integer.Preserve original relative order within each group.

S003 · implies

Before

position=1;raw fraction=[26, -2]

After

normalized=-13/1;integer=Yes

Conditions: none

A nonzero negative denominator is valid.Normalize to a reduced value with positive denominator;denominator1 means integer.Preserve original relative order within each group.

S005 · implies

Before

position=3;raw fraction=[-15, -31]

After

normalized=15/31;integer=No

Conditions: none

A nonzero negative denominator is valid.Normalize to a reduced value with positive denominator;denominator1 means integer.Preserve original relative order within each group.

Reverse checks

  • S005 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.
  • S004 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.
  • S003 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.
  • S002 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.
  • S001 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.

Result

([Yes, Yes, No, No], [1, -13], [14/29, 15/31])

The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
