Question

dau coroana ajutor......​

Answer 1

Explicație pas cu pas:

$\frac{21}{10} - \frac{9}{10} - \frac{7}{10} = \frac{5}{10} = \frac{1}{2}$

$\frac{27}{26} - \frac{11}{26} - \frac{3}{26} = \frac{13}{26} = \frac{1}{2}$

$\frac{35}{24} - \frac{19}{24} - \frac{5}{12} = \frac{35 - 19 - 10}{24} = \frac{6}{24} = \frac{1}{4}$
