Question

AJUTOR LA EXERCITIUL 2

Answer 1

Răspuns:

Explicație pas cu pas:

x = 11/6 iar y = 17/9

aduci la acelasi numitor si compari. E ok?

Answer 2

    x = $1\frac{5}{6}=\frac{11}{6}$

    y = $1\frac{8}{9}=\frac{17}{9}$

    a) x = $\frac{11}{6}=\frac{99}{54}$

    y = $\frac{17}{9}=\frac{102}{54}$

    x [] y

    $\frac{99}{54}<\frac{102}{54}$

    ⇒ x [<] y

    b) $\frac{17}{9}:[(\frac{11}{6})^{2}-\frac{17}{9}]$

    $\frac{17}{9}:(\frac{121}{36}-\frac{17}{9})$

    $\frac{17}{9}:(\frac{121}{36}-\frac{68}{36})$

    $\frac{17}{9}:\frac{53}{36}$

    $\frac{17}{9}*\frac{36}{53}$

    $\frac{612}{477}$

    $\frac{68}{53}$
