Question

should we change the sign of the number in multiplicative inverse
for example in 7/9 can we say -9/7 is its multiplicative inverse
plz say correctly​

Answer 1

Answer:

No, you must not change the sign in multiplicative inverse.

Step-by-step explanation:

7/9 × -9/7 = -1 not 1 ,

so , only reciprocal is needed . Don't change the signs

Answer 2

Answer:

multiplicative inverse =reciprocal

NO,you need not change the sign while reversing the numbers because it's not correct.

You can simply write it as 9/7.

This is because =

9/7=reciprocal=7/9...minus is only used in these cases when the denominator is 1 say 3/1=reciprocal=-1/3
