Three friends, Sita, Geeta and Reeta, share 7/8 of a cake. They wonder: 'When we add up our portions p, q, r, does (p + q) + r equal p + (q + r)?' Which property guarantees the answer is the same either way?

Question

Accepted Answer

Associative property of addition. The associative property of addition states (p + q) + r = p + (q + r); the grouping of addends does not change the total.

Three friends, Sita, Geeta and Reeta, share $\frac{7}{8}$ of a cake.
