The multiplicative inverse, or reciprocal, of a number 'a' is a number that when multiplied by 'a' equals 1.
To find the multiplicative inverse of -7/5, we need to find a number, let's call it 'x', that satisfies the equation (-7/5) * x = 1.
To solve for 'x', we can isolate it by multiplying both sides of the equation by the reciprocal of -7/5, which is -5/7:
(-7/5) * x * (-5/7) = 1 * (-5/7)
x = -5/7
Thus, the multiplicative inverse of -7/5 is -5/7.
