Question

name the property under mulplication use in each of the following
?_4/5*1=1*_4/5=-4/5​

Answer 1

Answer:

(i) -4/5 × 1 = 1 × -4/5 = -4/5 (ii) -13/17 × -2/7 = -2/7 × -13/17. (iii) -19/29 × 29/-19 = 1. ∴ 1 is the multiplicative identity in the above expression. Thus, the property of Multiplicative Identity is used here.
