The stretch of a spring in millimeters is proportional to the weight in grams attached to the end of the spring. Find the unit rate.

mm per gram
The unit rate is mm per gram.
To find the unit rate, we need to determine the amount of stretch in millimeters for each gram of weight. Since the stretch of the spring is proportional to the weight, we can express the unit rate as "mm per gram."
Therefore, the unit rate is mm per gram.
To find the unit rate in this scenario, we need to determine the amount of stretch in millimeters per gram of weight.
The given information states that the stretch of the spring in millimeters is proportional to the weight in grams. Proportional relationships can be expressed using ratios.
To calculate the unit rate, we divide the amount of stretch in millimeters by the weight in grams. Let's assume that the stretch of the spring is 20 millimeters and the weight attached is 100 grams:
Unit Rate = Stretch in millimeters / Weight in grams
= 20 millimeters / 100 grams
Unit Rate = 0.2 millimeters per gram
Therefore, the unit rate is 0.2 millimeters per gram, which means that for every gram of weight added to the spring, it stretches by 0.2 millimeters.
