Question

Calculați [0,(3)+1,(3):17supra2

Answer 1

Explicație pas cu pas:

$\bigg[0,(3) + 1,(3)\bigg] : \dfrac{17}{2} = \bigg[\dfrac{3}{9} + \dfrac{13 - 1}{9}\bigg] : \dfrac{17}{2} = \bigg[\dfrac{1}{3} + \dfrac{12}{9}\bigg] : \dfrac{17}{2} = \bigg(\dfrac{1}{3} + \dfrac{4}{3} \bigg) \cdot \dfrac{2}{17} = \dfrac{5}{3} \cdot \dfrac{2}{17} = \dfrac{10}{51}$

Answer 2

Răspuns:

$[0.(3) + 1.(3)] \div \frac{17}{2} \\ (\frac{3}{9} + \frac{13 - 1}{9} ) \div \frac{17}{2} \\( \frac{1}{3} + \frac{12}{9} ) \div \frac{17}{2} \\ ( \frac{1}{3} + \frac{4}{3} ) \div \frac{17}{2} = \frac{5}{3} \times \frac{17}{2} = \frac{10}{51}$
