Question

Multiplicative inverse of (-4/5 )2 is

Answer 1

Answer:

-4/5 × 2

= $\frac{-8}{5}$

Multiplicative inverse of any fraction is its reciprocal'

Therefore,

Multiplicative inverse = $\frac{5}{-8}$   or   $\frac{-5}{8}$

Answer 2

Answer:

$let \: multiplicative \: inverse \: of \: ( - \frac{4}{5} ) \times 2 \: is \: x \\ now \: (- \frac{4}{5} ) \times 2 \times x = 1 \\ = >( \frac{ - 8}{5} ) \times x = 1 \\ = > x = 1 \times \frac{ - 5}{8} \\ = > x = \frac{ - 5}{8}$

Therefore multiplicative of (-4/5) is (-5/8)
