Answer 1

Bună! ⭐

__________

  Calculați valoarea raportului numerelor în fiecare dintre cazurile:

$a)$ $12$ $si$ $3$

$\frac{12}{3} =4$

$b)$ $2\frac{1}{3}$ $si$ $3\frac{1}{2}$

$2\frac{1}{3} = \frac{2*3+1}{3} =\frac{7}{3}$

$3\frac{1}{2} =\frac{3*2+1}{2} =\frac{7}{2}$

$\frac{\frac{7}{3} }{\frac{7}{2} } =\frac{7}{3} *\frac{2}{7} =\frac{2}{3} =0,(6)$

$c)$ $12$ $si$ $\frac{1}{3}$

$\frac{12}{\frac{1}{3} } =12*\frac{3}{1} =36$

$d)$ $\frac{2}{7}$ $si$ $2$

$\frac{\frac{2}{7} }{2} =\frac{2}{7} *\frac{1}{2} =\frac{1}{7}$ ≈ $0,143$
