Răspuns:

Explicație pas cu pas:

[1,58(3) + 0,2(7) - 1,(6)] x 2,4​=[(1583-158)/900+(27-2)/90-(16-1)/9]x24/10=

[1425/900+25/90-15/9]x24/10= [(1425+250-1500)/900]x24/10= 175/900x24/10= 4200/9000= 42/90= 21/45=7/15

Answer 2

$(\frac{1583 - 58}{900} + \frac{27 - 2}{90} - \frac{16}{9} ) \times \frac{24}{10} =$

$( \frac{1525}{900} + \frac{25}{90} - \frac{16}{9} ) \times \frac{24}{10} =$

$( \frac{1525}{900} + \frac{250}{900} - \frac{1600}{900} ) \times \frac{24}{10} =$

$\frac{175}{900} \times \frac{24}{10} = \frac{4200}{9000} = 7/15$
