Answer 3

To solve the given expressions, we'll use the proportionality relationship:

$\frac{a}{b} = \frac{c}{d}$

First, let's solve for $a$ in each of the given expressions using the given ratios:

1. $\frac{242}{9} = \frac{97}{7}$ Solving for $a$: $a = \frac{242 \times 97}{9 \times 7} = 26.888...$

2. $\frac{97}{7} = \frac{83}{8}$ Solving for $a$: $a = \frac{97 \times 83}{7 \times 8} = 11.442...$

3. $\frac{83}{8} = \frac{123}{4}$ Solving for $a$: $a = \frac{83 \times 123}{8 \times 4} = 25.564...$

Now, let's approximate the values of $a$ to two decimal places:

1. $a \approx 26.89$
2. $a \approx 11.44$
3. $a \approx 25.56$

The values of $a$ are approximate and rounded to two decimal places.
