Question

dau coroana daca il faceti pe asta:

Answer 1

Răspuns:

Explicație pas cu pas:

$1\frac{2}{5} = \frac{7}{5}$

$4\frac{1}{7} = \frac{29}{7}$

$3\frac{1}{14} = \frac{43}{14}$

=> $\frac{7}{5} * (\frac{29}{7} - \frac{43}{14})$

amplificam 29/7 cu 2

=> $\frac{7}{5} * \frac{58-43}{14} = \frac{7}{5} * \frac{15}{14} = \frac{105}{70}$

= $\frac{3}{2}$
