Question

ajutor!!!! 15/16×12/25×1 întreg 1/9×6 intregi 3/4×2/11×8 intregi 1/4 dau coroana

Answer 1

$\frac{15}{16} \times \frac{12}{25} \times1 \frac{1}{9} \times 6 \frac{3}{4} \times \frac{2}{11} \times 8 \frac{1}{4} =$

15 si 25 se impart la 5 si ramane 3 si 5
16 si 12 la 4 si ramane 4 si 3


$\frac{3}{4} \times \frac{3}{5} \times \frac{1 \times 9 + 1}{9} \times \frac{6 \times 4 + 3}{4} \times \\ \frac{2}{11} \times \frac{8 \times 4 + 1}{4} =$


$\frac{9}{20} \times \frac{10}{9} \times \frac{27}{4} \times \frac{2}{11} \times \frac{33}{4} =$
9si 9 se impart la 9 si ramane 1 si 1
20 si 10 se impart la 10 si ramane 2 si 1
2 si 4 se impart la 2 si ramane 1 si 2


$\frac{1}{2} \times \frac{1}{1} \times \frac{27}{2} \times \frac{1}{11} \times \frac{33}{4} =$
33 si 11 se impart la 11 si ramane 3 si 1

$\frac{1}{2} \times \frac{1}{1} \times \frac{27}{2} \times \frac{1}{1} \times \frac{3}{4} = \\ \frac{(1 \times 1 \times 27 \times 1 \times 3)}{(2 \times 1 \times 2 \times 1 \times 4)} =$

$= \frac{81}{16}$
