To determine the correct phrase to insert in the statement "Two-thirds ___ StartFraction 8 Over 12 EndFraction", we need to evaluate the fraction \( \frac{8}{12} \) and compare it with two-thirds \( \frac{2}{3} \).
First, let's simplify \( \frac{8}{12} \): \[ \frac{8}{12} = \frac{2}{3} \] Therefore, both fractions are equivalent, meaning that:
\[ \frac{2}{3} = \frac{8}{12} \]
So the appropriate phrase to insert is "is equal to".
Thus, the complete statement is:
Two-thirds is equal to \( \frac{8}{12} \).
