Conceptos:fracción

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 .
