Question

Name the property of multiplication of rational numbers illustrated by the following statements:
(i) $\frac{-5}{16}\times \frac{8}{15}=\frac{8}{15}\times \frac{-5}{16}$

(ii) $\frac{-17}{5}\times 9=9\times \frac{-17}{5}$

(iii) $\frac{7}{4}\times \left(\frac{-8}{3}+\frac{-13}{12}\right)=\frac{7}{4}\times \frac{-8}{3}+\frac{7}{4}\times \frac{-13}{12}$

(iv) $\frac{-5}{9}\times \left(\frac{4}{15}\times \frac{-9}{8}\right)=\left(\frac{-5}{9}\times \frac{4}{15}\right)\times \frac{-9}{8}$

(v) $\frac{13}{-17}\times 1=\frac{13}{-17}=1\times \frac{13}{-17}$

(vi) $\frac{-11}{16}\times \frac{16}{-11}=1$

(vii) $\frac{2}{13}\times 0=0=0\times \frac{2}{13}$

(viii) $\frac{-3}{2}\times \frac{5}{4}+\frac{-3}{2}\times \frac{-7}{6}=\frac{-3}{2}\times \left(\frac{5}{4}+\frac{-7}{6}\right)$
