Question

Calculați: 3/7:14; 1întreg 5/9:18; 2întregi : 36/25; 1întreg 2/17:34; 2întregi 8/9:27/5

Answer 1

$\frac{3}{7} :14= \frac{3}{7} * \frac{1}{14} = \frac{3}{98}$
$1 \frac{5}{9} :18= \frac{1*9+5}{9} * \frac{1}{18} = \frac{14}{9} * \frac{1}{18} = \frac{7}{81}$
$2: \frac{36}{25} =2* \frac{25}{36} = \frac{25}{18}$
$1 \frac{2}{17} :34= \frac{1*17+2}{17} * \frac{1}{34} = \frac{19}{17} * \frac{1}{34} = \frac{19}{578}$
$2 \frac{8}{9} : \frac{27}{5} = \frac{2*9+8}{9} * \frac{5}{27} = \frac{26}{9} * \frac{5}{27} = \frac{130}{243}$

Answer 2

3/7:14=3/7:14/1=3/7x1/14=3/98

1intreg 5/9:18=14/9:18=14/9:18/1=14/9x1/18=7/1x1/1=7/1=1

1intreg2/17:34=19/17:34=19/17:34/1=19/17x1/34=19/578

2intregi 8/9:27/5=26/9:27/5=26/9x5/27=130/243
