Query: Ratios of periods for tensor product motives   In this article we prove some period relations for the ratio of Deligne's
periods for certain tensor product motives. These period relations give a
motivic interpretation for certain algebraicity results for ratios of
successive critical values for Rankin-Selberg L-functions for ${\rm GL}_n
\times {\rm GL}_{n'}$ proved by G\"unter Harder and the second author.
