Answer 1

Răspuns:

1,996 aproximativ 2

Explicație pas cu pas:

$\frac{\frac{\frac{252}{100} }{\frac{56}{10} } +\frac{23}{10} }{\frac{62}{10} } *\frac{45}{10}\\ \frac{\frac{252 }{560 } +\frac{23}{10} }{\frac{62}{10} } *\frac{45}{10}\\ \frac{\frac{252 +1288}{560 } }{\frac{62}{10} } *\frac{45}{10}\\\frac{1540*10}{560 *62} *\frac{45}{10}\\\frac{693000}{347200}=\frac{6930}{3472}=1,996=2$
