Simplify smartly using properties: 7/15 × 9/14 × 15/7. Rearrange the factors (commutative and associative) and find the product.

Question

Accepted Answer

9/14. Group 7/15 × 15/7 = 1 (a number times related factors). Then 1 × 9/14 = 9/14. Commutativity/associativity allow this regrouping.

Simplify smartly using properties:
$\frac{7}{15} \times \frac{9}{14} \times \frac{15}{7}$ .
