Answer 1

Răspuns:

Explicație pas cu pas:

$\frac{7}{5}$+9( 5-3-6)=> $\frac{7}{5}$+9× (-4)=> $\frac{7}{5}$ -36=> $\frac{7-252}{5}$= $-\frac{245}{5}$= 49

1.44+ 3[4( 1.5- 1)]=> 1.44+ 3(4* 0.5)=> 1.44+ 3*2=> 1.44+ 6=7.44

$\frac{1}{2}$+ 2* 3.25=> $\frac{1}{2}$+ 6.5=> $\frac{1+13}{2}$= 7

0.6+ $\frac{3}{5}$*$\frac{5}{6}$+$\frac{4}{5}$ => 0.6+ $\frac{1}{2}$+ $\frac{4}{5}$=> 0.6+ $\frac{5+8}{10}$=> 0.6+ 1.3= 1.9

-3.25+ 3* $\frac{3.4-3}{2}${aici este 3.4-3 supra 2}=> -3.25+ $\frac{3*0.4}{2}${ 3*0.4 supra 2}=> -3.25+ $\frac{1.2}{2}$=> $-\frac{6.5+1.2}{2}$=> -$-\frac{7.7}{2}$

-0.75+ $\frac{1}{12}$*$\frac{1}{6}$=> -0.75+ $\frac{1}{72}$=> $-\frac{54+1}{72}$= $-\frac{55}{72}$
