15 paperclips or equal size weigh 2 grams altogether. is the number of paperclips proportional to their weight?

Proportionality indicates how quantity vary in relation with other quantities. There are two types of proportionality, that is direct proportionality where an increase or a decrease in a quantity causes a corresponding increase or decrease in the other variable and inverse proportionality where decrease in a variable causes an increase in the other variable and vicevarsa. In this case the 15 paperclips have a total weight of 2 grams therefore each clip contributes a weight of 0.0133 grams, thus increasing the paperclips also increases the total weight. Thus, the number of paper clips is direct proportional to the total weight
