Answer
true
Work Step by Step
To determine whether $\frac{2\frac{5}{8}}{3\frac{1}{4}} = \frac{21}{26}$ is true, determine whether the cross products are equal.
$2\frac{5}{8}\times26$ = $3\frac{1}{4}\times21$
$\frac{21}{8}\times\frac{26}{1}$ = $\frac{13}{4}\times\frac{21}{1}$
$\frac{546}{8}$ = $\frac{273}{4}$
$\frac{546\div2}{8\div2}$ = $\frac{273}{4}$
$\frac{273}{4}$ = $\frac{273}{4}$
The cross products are equal so the proportion is true.
