Answer
False/Not true
Work Step by Step
First, multiply by 4 on both sides to get rid of the 4 in the denominator on the left:
$\frac{7}{4}\cdot 4 = \frac{5}{3}\cdot 4 \rightarrow 7 = \frac{20}{3}$
Then, multiply by 3 on both sides to get rid of the 3 in the denominator on the right:
$7\cdot 3 = \frac{20}{3}\cdot 3 \rightarrow 21 = 20$
20 does not equal 21, so the proportion is not true.
