The leaves of a poison ivy plant are found in clusters of 3. one poison ivy plant has a total of 21 leaves. how many leaf clusters does this plant have?

Using the proportional principle, the number of clusters which would produce a total of 21 leaves is 7.

Given the Parameters :

The number of clusters which produce leaves which totals 21 can be calculated thus :

1 cluster = 3 leaves

x clusters = 21 leaves

Cross multiply

3x = 21 × 1

3x = 21

x = 21 / 3

x = 7

Therefore, 7 clusters will make a total of 21 leaves.
