When additive inverse of -45is added to multiplicative identity of rational numbers, we get
15
-15
145
-145
We have, an additive inverse of -45is45 (since -45+45=0)
Multiplicative identity of rational numbers=1.
Now,
45+1=45+11=45+1×51×5=45+55=4+55=95=145
Hence, option(c) is correct.
Which of the following statements is not true?
When we add 14 to its additive inverse, we get additive identity.
What should be multiplied with 14 to get the multiplicative identity?
When we add 14 to its additive inverse we get additive identity.
Question 11 If x + 0 = 0 + x = x, which is rational number, then 0 is called: (a) identity for addition of rational numbers. (b) additive inverse of x. (c) multiplicative inverse of x. (d) reciprocal of x.
