Answer 1

Answer:

0.49 °C

Step-by-step explanation:

$Given, \: \\ Temperature \: of \: the \: city \: over \: 4 \: days: \\ 2.34 \: °C, \frac{ - 2}{7} °C, - 0.45°C, \frac{3}{8} °C \\ So,\:average \: temperature\\= \frac{2.34 \: °C + (\frac{ - 2}{7}) °C + (- 0.45°C) + \frac{3}{8} °C}{4} \\ = \frac{\frac{117}{50} \: °C + (\frac{ - 2}{7}) °C + (- \frac{9}{20} °C) + \frac{3}{8} °C}{4} \\ = \frac{ [\frac{117}{50} \: + (\frac{ - 2}{7}) + (- \frac{9}{20} ) + \frac{3}{8}] °C}{4}\\ = \frac{ \frac{2771}{1400} °C}{4}\\ =\frac{2771}{5600} \\≈ 0.494 \\ ≈0.49°C$
