Question

Name the property under multiplication used in each of the following. 

(i)\(\frac{-4}{5}×1=1×\frac{-4}{5}=-\frac{4}{5} \)

(ii) \(-\frac{13}{17}×\frac{-2}{7}=\frac{-2}{7}×\frac{-13}{17}\)

(iii) \(\frac{-19}{29}×\frac{29}{-19}=1.\)

Answer 1

(i) \(\frac{-4}{5}×1=1×\frac{-4}{5}=-\frac{4}{5}\)

1 is the multiplicative identity.

(ii) Commutativity
