alleryWhich property is used to write a × (b + c) = ab + ac for any three rational numbers a, b, c?
ACommutativity
BAssociativity
CClosure
DDistributivity of multiplication over addition
Answer & Solution
Correct answer: D. Distributivity of multiplication over addition
**The distributive law for rationals:** a(b + c) = ab + ac (and likewise a(b − c) = ab − ac).
It links multiplication with addition/subtraction.
