Answer 2

It seems like you've provided three mathematical expressions or equations. Let's break down each one:

1. $\frac{17}{3} : \frac{21}{4} = \frac{x}{214}$ This equation involves division of fractions. To solve for $x$, you can cross-multiply and then solve for $x$: $x = \frac{17}{3} \times \frac{214}{21}$

2. $\frac{x}{5.7} = \frac{4.9}{0.2}$ This equation involves division of decimals. To solve for $x$, you can cross-multiply and then solve for ( x : $x = \frac{4.9 \times 5.7}{0.2}$

3. $\frac{3}{4.5} = \frac{5 \frac{1}{7}}{x}$ This equation involves a mixed number on the right side. To solve for $x$, first convert the mixed number to an improper fraction, then cross-multiply and solve for ( x : $x = \frac{5 \frac{1}{7}}{ \frac{3}{4.5}}$

Please perform the necessary calculations to get the numerical values of $x$ in each of these equations.
