Question

Multiplicative inverse of 5*-9/10

Answer 1

Step-by-step explanation:

5 * $\frac{-9}{10}$

=$\frac{-45}{10}$

Multiplicative inverse of this fraction is when the places of the numerator and denominator are switched.

Therefore,

multiplicative inverse of the above is:-

$\frac{-10}{45}$  (the negative sign stays at the top)

=$\frac{-2}{9}$ (on reducing it to lowest form by dividing by 5)
