Question

Name the property under multiplication used in the following.
$-\frac{4}{5}\times 1=1\times \frac{-4}{5}=-\frac{4}{5}$

Answer 1

Here, the commutative property for multiplication is used,

i.e., $(a\times b)=(b\times a)$
By replacing $a=\frac{-4}{5}$ and $b=1$, we get given expression as
$-\frac{4}{5}\times 1=1\times \frac{-4}{5}=-\frac{4}{5}$
Hence, the commutative property under multiplication is used.
