Find the difference of additive inverse and multiplicative inverse of 5/9​

1 thought on “Find the difference of additive inverse and multiplicative inverse of 5/9​”

1. Step-by-step explanation:

   Additive inverse of

   5

   9

   is

   −

   5

   9

   and multiplicative inverse of

   5

   9

   is

   9

   5

   Explanation:

   Additive inverse of a number is the number which when added to it makes the sum zero

   0

   – the additive identity element . Observe that

   0

   is known as additive identity element as when this is added to any number, it results in the same number.

   Obviously additive inverse of

   x

   is

   −

   x

   and hence additive inverse of

   5

   9

   is

   −

   5

   9

   .

   Multiplicative inverse of a number is the number which when multiplied to it makes the product one

   1

   – the multiplicative identity element . Observe that

   1

   is known as multiplicative identity element as when this when multiplied to any number, results in the same number.

   Obviously multiplicative inverse of

   x

   is

   1

   x

   and hence additive inverse of

   5

   9

   is

   1

   5

   9

   =

   9

   5
