Question

What is the standard form of $\frac{-12}{-30}$

• A. $\frac{2}{-5}$
• B. $\frac{2}{5}$
• C. $\frac{-2}{5}$
• D. $\frac{-5}{2}$

Answer 1

The correct option is B $\frac{2}{5}$

To express $\frac{-12}{-30}$ in standard form.
The denominator is negative.
Therefore, multiplying the numerator and the denominator by (-1).
= $\frac{(-12\times (-1\left)\right)}{(-30\times (-1\left)\right)}$ = $\frac{12}{30}$
Now, dividing the numerator and the denominator by 6,
$\frac{12}{30}$ = $\frac{(12÷6)}{(30÷6)}$ = $\frac{2}{5}$
Therefore, the standard form of the given number is $\frac{2}{5}$.
