$1.1$ $1.1$

Explanation:

$\frac{- 1.21}{- 1.1} = \frac{121 \cdot 0.01}{11 \cdot 0.1}$ $(-1.21)/(-1.1) = (121*0.01)/(11*0.1)$
But remember that $0.1 = \frac{1}{10}$ $0.1=1/10$ then

$\frac{- 1.21}{- 1.1} = \frac{11 \cdot \frac{1}{100}}{\frac{1}{10}}$ $(-1.21)/(-1.1) = (11*1/100)/(1/10)$
$= \frac{11 \cdot 10}{100}$ $= (11*10)/100$
$= \frac{11}{10}$ $=11/10$

$= 1.1$ $=1.1$
