Question

Scrie cate 3 fractii egale cu fractiile: 
a) 12supra28
b) 125supra 15
c)2la puetrea3 supra 8
d) 1 supra 3

Answer 1

Răspuns:

$\frac{12}{28} =\frac{6}{14} =\frac{3}{7} =\frac{24}{56} \\ \\ \frac{125}{15} =\frac{250}{30}=\frac{25}{3} =\frac{75}{9} \\ \\ \frac{2^{3} }{8} = \frac{8}{8}= \frac{24}{24} =\frac{48}{48} \\ \\ \frac{1}{3} =\frac{4}{12} =\frac{6}{18} =\frac{8}{24}$

fractii egale inseamna ca   daca avem  $\frac{a}{b} =\frac{c}{d}$   ⇒  axd=bxc
