Answer 2

To solve this expression, let's break it down step by step:

1. $2.07 \times \frac{9}{2} - 21.678$ $= 2.07 \times 4.5 - 21.678$ (since $\frac{9}{2} = 4.5$) $= 9.315 - 21.678$ (multiplication first) $= -12.363$

2. $1 \frac{1}{5} + 22.236 \div 1 \frac{1}{100}$ $= 1.2 + 22.236 \div 1.01$ (convert mixed numbers to improper fractions) $= 1.2 + 22.0$ (since $22.236 \div 1.01 \approx 22.0$) $= 23.2$

Now, let's put it all together:

$-12.363 + 23.2 \approx 10.837$

The result is approximately $10.837$.
