# Tell what property allows you to compute 1/3 × (6 × 4/5) as (1/3 × 6) × 4/3

**Solution:**

A rational number is a number that is of the form p/q where p and q are integers and q is not equal to 0.

According to the associative property of multiplication,

(a × b) × c = a × (b × c)

Thus, by using the associativity of multiplication we see that,

1/3 × (6 × 4/5) = (1/3 × 6) × 4/3

Hence, the associative property of multiplication has been used in the given expression.
