#### Answer

$\frac{11}{4} = \frac{5}{2}$
False

#### Work Step by Step

x is to y is the same as $\frac{x}{y}$
To determine if a proportion is true, we have to find if the cross products are equal.
The cross products of $\frac{a}{b}=\frac{c}{d}$ are $a \cdot d$ and $b \cdot c$.
Eleven is to four as five is to two is the same as $\frac{11}{4} = \frac{5}{2}$
This proportion is false because $11*2=22, 5*4=20, 22 \neq 20$
