1) $\frac{2.73}{1.3}$

$= > \frac{( \frac{273}{100}) }{( \frac{13}{10} )}$

$= > \frac{273}{100} \times \frac{10}{13}$

$= > \frac{273}{10} \times \frac{1}{13}$

$= > 2.1$

2) 11.2 × 0.15

$= > \frac{112}{10} \times \frac{15}{100}$

$= > \frac{112 \times 15}{1000}$

$= > \frac{1680}{1000} \\ = > \frac{168}{100}$

$= > 1.68$
