Answer
True
Work Step by Step
First, multiply by 2 on both sides to get rid of the 2 in the denominator on the left:
$\frac{8.2}{2}\cdot2 = \frac{16.4}{4}\cdot2 \rightarrow 8.2 = \frac{16.4}{2}$
Then, multiply by 2 on both sides to get rid of the 2 in the denominator on the right:
$8.2\cdot2 = \frac{16.4}{2}\cdot2 \rightarrow 16.4 = 16.4$
16.4 is equal to 16.4, so the proportion is true.
