Final answer:
When converting from smaller units to larger units, divide by 1,000 and move the decimal point three places to the left, which corresponds to moving left to right on a unit chart, effectively taking zeros away.
Step-by-step explanation:
When converting from a smaller unit to a larger unit, you must divide and move the decimal point to the left. This process is necessary because you are making each unit smaller in the larger context. For example, there are 1,000 milliliters in a liter, so to convert milliliters to liters, you divide by 1,000 and move the decimal point three places to the left. Likewise, there are 10 millimeters in a centimeter, and to convert millimeters to centimeters, you move the decimal point one place to the left. Similarly, with 1,000 meters in a kilometer, you would divide by 1,000 and move the decimal point three places to the left for conversions from meters to kilometers.
Considering the provided options, dividing by 1,000 and moving from the right to the left on the chart while taking zeros away correctly describes the process of going from a smaller unit to a larger unit. Therefore, the correct answer would be: b) Divide by 1,000; move left to right
