Ordered representations=[-7/1, 10/-2, 6/13, -7/-15] all have nonzero denominators. Give (integer-membership Yes/No list, integer values, reduced noninteger values), preserving original order within groups.
G001 — Ordered representations=[-7/1, 10/-2, 6/13, -7/-15] all have nonzero denominators. Give (integer-membership Yes/No list, integer values, reduced noninteger values), preserving original order within groups.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.
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.
Rule: integer_arithmetic_scope · Uses: G001
Before
position=0;raw fraction=[-7, 1]
After
normalized=-7/1;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.
