Is -5 2/3 the multiplicative inverse of 3/-17? ​<br><br>PLEASE HELP!!
Ostrovityanka [42]

Answer:

Yes

Step-by-step explanation:

Multiplicative Inverse of rational number:

       When we multiply a rational number and its multiplicative inverse, we get 1

     \sf -5 \dfrac{2}{3}=\dfrac{-17}{3}

  Now,multiply this with (3/-17)

          \sf \dfrac{-17}{3}*\dfrac{3}{-17} = 1

So, -5 2/3  is the multiplicatice inverse of 3/-17
