Question

When do we say that an algebraic fraction is in its lowest form?

• A. If its numerator and denominator have a common factor.
• B. If it is in the form of $\frac{xa}{yb}$
• C. If it is in the form of $\frac{xa}{ycb}$
• D. If its numerator and denominator have no common factor.

Answer 1

The correct option is D

If its numerator and denominator have no common factor.

An algebraic fraction is said to be in its lowest form if its numerator and denominator have no common factor.

$\Rightarrow$ Both the numerator and denominator should be divided by the common terms or factors present in them.

$\Rightarrow$ $\frac{xa}{xb}=\frac{a}{b}$
