Question

The product of 5/7 and additive inverse of (-3/8) is ​

Answer 1

Answer:

The product is -1.

Step-by-step explanation:

A number gives 0 ( additive identity ) after adding with its Additive inverse and it gives 1 ( multiplicative inverse ) after multiplication with its multiplicative inverse.

Here, the given number is,

Let, x be the additive inverse of the number,

Thus, the additive inverse of -3/7 is 3/7.

Now, let the y be the multiplicative inverse of -3/7,

Thus, the multiplicative inverse of -3/7 is -7/3.

Hence, the product of additive inverse and multiplicative inverse of minus 3 upon 7
