Question

gasiti o fractie mai mare de 10/21 decat fractia 7/5 si o fractie de 39/28 mai mica decat fractia 13/14

Answer 1

$\frac{7}{5} \times \frac{10}{21} = \frac{7 \times 10}{5 \times 21} = \frac{70}{105} = \frac{14}{21} = \frac{2}{3}$

$\frac{13}{14} \div \frac{39}{28} = \frac{13}{14} \times \frac{28}{39} = \frac{13 \times 28}{14 \times 39} = \frac{364}{546}$

$= \frac{182}{273}$
