0,(2)supra 0,(3)=5/×​

Răspuns:

[tex]0.(2) = \frac{2}{9} \\ 0.(3) = \frac{3}{9} \\ \frac{ \frac{2}{9} }{ \frac{3}{9} } = \frac{2}{3}

coronița?

Răspuns:

x=7,5

Explicație pas cu pas:

[tex] \frac{ \frac{2}{9} }{ \frac{3}{9} } = \frac{5}{x} [/tex]

[tex] \frac{2}{9} \div \frac{3}{9} = \frac{5}{x} [/tex]

[tex] \frac{2}{9} \times 3 = \frac{5}{x} [/tex]

[tex] \frac{6}{9} = \frac{5}{x} [/tex]

[tex]x = \frac{9 \times 5}{6 } \\ x = \frac{45}{6 } = 7.5[/tex]
