Final answer:
To maintain the same ratio after multiplying j by 17, k should be multiplied by the reciprocal of 17 (1/17).
Step-by-step explanation:
To maintain the same ratio after multiplying j by 17, k should be multiplied by the reciprocal of 17. The reciprocal of 17 is 1/17, so k should be multiplied by 1/17 to maintain the same ratio. In other words, k multiplied by 1/17 is the same as j multiplied by 17.
