6th Grade Application of Algebraic Ideas in Number Theory: Problem 2

Problem: There is a 1263 mm long steel piece. It needs to be cut into 64 mm long pieces and 90 mm long pieces. Every single time a cut is made, 1 mm of steel is wasted. If we want to keep the amount of wasted steel to a minimal amount, how many 64 and 90 mm long pieces should be cut?

Key: Translate relationships given in the problem into relationships using math (equivalences / inequalities)
