Don't use a calculator

$$ I just use the fact that $\frac{272.5}{275} < \frac{273}{275} < \frac{275}{275}$ , therefore, we simplify into $\frac{109}{110} < \frac{273}{275} < 1$ . I think it's not that hard to obtain $109$ divided by $110$ without using a calculator or maybe you can easily guess that $\frac{109}{110} \approx 0.99$ . $\text{\# }\mathbb{Q}.\mathbb{E}.\mathbb{D}.\text{\#}$
