Answer 1

$\dfrac{11}{9} + \dfrac{4}{9} = \dfrac{11 + 4}{9} = \dfrac{15^{(3} }{9} = \dfrac{5}{3}$

$\dfrac{13}{9} + \dfrac{4}{9} = \dfrac{13 + 4}{9} = \dfrac{17}{9}$

$\dfrac{17}{9} + \dfrac{4}{9} = \dfrac{17 + 4}{9} = \dfrac{21^{(3} }{9} = \dfrac{7}{3}$

$\dfrac{23}{9} + \dfrac{4}{9} = \dfrac{23 + 4}{9} = \dfrac{27}{9} = 3$

$\dfrac{21}{9} + \dfrac{4}{9} = \dfrac{21 + 4}{9} = \dfrac{25}{9}$

$\dfrac{32}{9} + \dfrac{4}{9} = \dfrac{32 + 4}{9} = \dfrac{36}{9} = 4$

Answer 2

Răspuns:

$\frac{11}{9} + \frac{4}{9} = \frac{15}{9} {}^{(3} = \frac{5}{3}$

$\frac{13}{9} + \frac{4}{9} = \frac{17}{9}$

$\frac{17}{9} + \frac{4}{9} = \frac{21}{9} {}^{(3} = \frac{7}{3}$

$\frac{23}{9} + \frac{4}{9} = \frac{27}{ \not9} {}^{(9} = 3$

$\frac{21}{9} + \frac{4}{9} = \frac{25}{9}$

$\frac{32}{9} + \frac{4}{9} = \frac{36}{ \not9} {}^{(9} = 4$

Explicație pas cu pas:

Cu x mai mare decât y:

$x + y$

Cu x mai mic decât y:

$y - x$

De x ori mai mare ca y:

$y \times x$

De x ori mai mic decât y:

$y \div x$
