Answer 1

Răspuns:

Explicație pas cu pas:

Bagam intregii in fractie dupa formula

$x\frac{z}{y} =\frac{xy+z}{y}$

$\frac{12}{10} (\frac{5}{2} -\frac{4}{3} )^{2} \cdot\frac{5}{42} +\frac{29}{36}$

aducem la acelasi numitor comun in paranteza, numitor 6

$\frac{12}{10} (\frac{15}{6} -\frac{8}{6} )^{2} \cdot\frac{5}{42} +\frac{29}{36}$

$\frac{12}{10} \cdot (\frac{7}{6} )^{2} \cdot\frac{5}{42} +\frac{29}{36}$

$\frac{12}{10} \cdot \frac{49}{36} \cdot\frac{5}{42} +\frac{29}{36}$

$\frac{1}{2} \cdot \frac{7}{3} \cdot\frac{1}{6} +\frac{29}{36}=\frac{7}{3}+ \frac{29}{36}=\frac{36}{36} =1$
