Answer:
Numbering the steps
Step-by-step explanation:
Procedural texts are texts that explain how something is done step by step. Numbering the steps is what would make the given procedural text most effective because that would make it easier to follow them. Without numbers or bullets, we can lose track of the steps we've mastered and waste time searching for the step we need to master next each time we read the text. That's why turning the step list into a numbered or bulleted list would make the text more effective.
