# The standard form of rational number -1 is ___.

**Solution:**

Given, the __rational number__ is -1

We have to find the standard form of rational number -1.

We know that, to reduce the rational number to its standard form, we divide its numerator and denominator by their __HCF__

HCF of 1 = 1

Now, the standard form of -1 = -1/1 = -1

Therefore, the standard form of -1 is -1.
