Question

1. which is not a step when writing a conversion fact in the si system?

multiply the number 1 by a factor of 20 for each column you move.
identify your starting measurement.
use the prefix table to count the number of columns between your starting measurement and your goal measurement.
identify your goal measurement.

Explanation:

In the SI system, conversion factors are based on powers of 10 (like multiplying by 10, 100, 1000, etc., or their reciprocals), not by a factor of 20. The other steps (identifying starting and goal measurements, using prefix table to count columns between them) are part of SI unit conversion. So the step "Multiply the number 1 by a factor of 20 for each column you move" is not a valid step in SI system conversion.

Answer:

A. Multiply the number 1 by a factor of 20 for each column you move
