Question

standard form 8/-18 is​

Answer 1

Answer:

$\frac{8}{ - 18} = \frac{4}{ - 9} = \frac{ - 4}{9}$

Answer 2

Answer:

Thus, we get the standard form of a rational number $\frac{8}{-18}$ is $-\frac{4}{9}.$

Step-by-step explanation:

• As per the question we have to evaluate the given data.

        Given data:- $\frac{8}{-18}.$

        To find:- Convert $\frac{8}{-18}$in standard form.

        Solution:-

• We know that Rational number is known as standard form.
• Usually, $\frac{a}{b}$ is said to be a standard form.
• Since the denominator, -18 has a negative sign multiply both numerator and denominator with -1 to make it positive.

         $=\frac{8}{-18} \\\\=\frac{8\times(-1)}{-18\times(-1)} \\\\=\frac{-8}{18}$

• Now find the greatest common factor (GCD)of both numerator and denominator.
• GCD(8,18)=2.
• Then multiply and divide both numerator and denominator by 2.

        we get,

        $=\frac{-8}{18}\\\\=\frac{((-8)\div2)}{18\div2} \\\\=-\frac{4}{9}$
