First write -0.25 as the fraction -1%2F4


Now to find the multiplicative inverse, simply flip the fraction to get -4%2F1 or -4


So the multiplicative inverse of -0.25 is -4


Check:

Simply multiply the two numbers -0.25 and -4 to get %28-0.25%29%2A%28-4%29=1

Since their product is 1, this means that -4 is the multiplicative inverse of -0.25 (and vice versa).
