What is multiplicative inverse?

• A Multiplicative inverse is a number opposite or a reciprocal to the original number.
• When it is multiplied by the original number the result is 1.
• if x is a number then its multiplicative inverse is denoted by 1/x.
• For example, the multiplication inverses of 5, 1/7, and -6/11 are 1/5, 7, and 11/-6.

Answer 2

-4/7 is the multiplicative inverse of -7/4.

• The number that when multiplied by the given number gives identity or one is known as multiplicative inverse.
• For example, if x is the given number, 1/x is its multiplicative inverse.
• Because x*(1/x) = 1
• Multiplying any number with its inverse gives you identity.
• So basically you are taking the inverse of the number and multiplying it.
• So it is called multiplicative inverse.
• In this case, (-7/4)*(-4/7) is 1

Hence -4/7 is the multiplicative inverse of -7/4.
