Question

Which of the following rational numbers is in the standard form?

• A. $-\frac{9}{28}$
• B. $-\frac{26}{78}$
• C. $-\frac{14}{16}$
• D. $\frac{48}{96}$

Answer 1

The correct option is A $-\frac{9}{28}$

A rational number $\frac{a}{b}$ is said to be in the standard form if b is positive and the integers a and b have no common divisor other than 1. Here, $-\frac{9}{28}$ has only 1 as a common factor. Therefore, $-\frac{9}{28}$ is in its standard form.
