Question

Va rog frumos dacă m-a puteți ajuta
3- 5 supra 7 si 2 + 3 supra 4 + 1 supra 2

Answer 1

$3 - \frac{5}{7} = \frac{21}{7} - \frac{5}{7} = \frac{16}{5}$

$2 + \frac{3}{4} + \frac{1}{2} = \frac{8}{4} + \frac{3}{4} + \frac{2}{4} = \frac{13}{4}$

Answer 2

Răspuns :

$3 + \frac{5}{7} =$

$\frac{3}{1} + \frac{5}{7} =$

$\frac{21}{7} + \frac{5}{7} =$

$\frac{26}{7}$

$2 + \frac{3}{4} + \frac{1}{2} =$

$\frac{2}{1} + \frac{3}{4} + \frac{1}{2} =$

$\frac{8}{4} + \frac{3}{4} + \frac{2}{4} =$

$\frac{13}{4}$
