To find the range of the weights of the apples, you subtract the smallest weight from the largest weight.
The weights given are:
- Smallest weight = 70 grams
- Largest weight = 120 grams
Now, calculate the range:
Range = Largest weight - Smallest weight
Range = 120 g - 70 g
Range = 50 g
Therefore, the range of the apples' weights is 50 grams.
