Find the multipacative inverse of the number
-18
(-18)(?) = 1 ?
18?
no, (-18)(18) would be - 324 , not 1
what about (-18)(-1/18) ?
To find the multiplicative inverse of a number, you need to find another number that, when multiplied by the original number, equals 1.
In this case, we want to find the multiplicative inverse of -18. Let's call the multiplicative inverse x.
So, we have:
-18 * x = 1
To solve for x, we need to isolate it on one side of the equation.
Dividing both sides of the equation by -18, we get:
x = 1 / -18
Simplifying the right side of the equation, we have:
x = -1/18
Therefore, the multiplicative inverse of -18 is -1/18.
You can verify this by multiplying -18 by -1/18. The result would be 1.
