Question

calculati: 2/3×9/16×32/27; 22/39×26/55×3/4; 7/10×5/77×25/420×0/1250​

Answer 1

$\frac{2}{3} \times \frac{32}{27}$

înmulțim și ne dă

$\frac{64}{81}$

$\frac{22}{39} \times \frac{26}{55} \times \frac{3}{4}$

inmultim

$\frac{572}{2145} \times \frac{3}{4}$

$\frac{1716}{8580}$

$\frac{7}{10} \times \frac{5}{77} \times \frac{25}{420} \times \frac{0}{1250}$

$\frac{35}{770} \times \frac{25}{420} \times \frac{0}{1250}$

$\frac{875}{323.400} \times \frac{0}{1250}$

$\frac{0}{404250000} = 0$

ok ;-;
