Cada fracción se reduce al mismo valor

Each fraction reduces to the same value

\dfrac{2}{20} = \dfrac{1}{10}

y

\dfrac{3}{30} = \dfrac{1}{10}

\dfrac{2}{20} = \dfrac{1}{10}

and

\dfrac{3}{30} = \dfrac{1}{10}

Cada fracción es igual a

\dfrac{1}{10} = 0.1,

ya que

\dfrac{2}{20} = \dfrac{3}{30} = \dfrac{1}{10}.

Así que la suma es

0.1 + 0.1 + 0.1 = 0.3.

Por lo tanto, la respuesta correcta es D.

Each fraction equals

\dfrac{1}{10} = 0.1,

since

\dfrac{2}{20} = \dfrac{3}{30} = \dfrac{1}{10}.

So the sum is

0.1 + 0.1 + 0.1 = 0.3.

Thus, the correct answer is D .
