Theory & Formula
What Are Fractions?
A fraction represents part of a whole. The numerator counts the parts you have, while the denominator shows how many equal parts make the whole.
Visual Representation
Fraction bars divide a whole into equal segments and highlight the portion specified by the numerator.
Equivalent Fractions
Multiply or divide the numerator and denominator by the same nonzero number to obtain an equivalent fraction.
\(\frac{1}{2} = \frac{2}{4} = \frac{3}{6} = \frac{4}{8}\)Concept check
Is 2/4 the same value as 1/2?
