Answer 2

Answer:

The standard form of the rational number -18/45 is -2/5.

Step-by-step explanation:

The given number is -18/45.

It is a rational number that is negative.

A rational number is a real number which is in the form p/q where p is the numerator and q is the denominator and q $\neq$ 0.

We need to evaluate the standard form of the given number.

The standard form of any rational number may be regarded as its simplest form.

So, here we go,

We divide the numerator and the denominator by 3, then we get

$=\frac{-18}{45} = \frac{\frac{-18}{3} }{\frac{45}{3} } = \frac{-6}{15}$

We again divide the numerator and the denominator by 3, so we have;

$= \frac{-6}{15} =\frac{-2}{5}$

This is the standard form of -18/45.

Hence, the standard form of the rational number -18/45 is -2/5.
