Question

Va rog foarte mult!!! Trebuie sa il predau astazi. DOAR EXERCITIUL 1. DAU 40 DE PUMCTE SI COROANA.

Answer 1

$\frac{ \frac{71}{100} - \frac{1}{4} \times (15 - 3 \times \frac{1}{2} \times \frac{5}{6}) }{ \frac{71}{100} + \frac{1}{4} \times( \frac{38}{3} - \frac{77}{9} ) \times \frac{9}{21} } \div \frac{7}{16}$

$\frac{ \frac{71}{100} - \frac{1}{4} \times (15 - \frac{1}{2} \times \frac{5}{2}) }{ \frac{71}{100} + \frac{1}{4} \times \frac{37}{9} \times \frac{9}{21} } \div \frac{7}{16}$

$\frac{ \frac{71}{100} - \frac{1}{4} \times (15 - \frac{5}{4} )}{ \frac{71}{100} + \frac{1}{4} \times 37 \times \frac{1}{21} } \div \frac{7}{16}$

$\frac{ \frac{71}{100} - \frac{1}{4} \times \frac{55}{4} }{ \frac{71}{100} + \frac{37}{84} } \div \frac{7}{16}$

$\frac{ \frac{71}{100} - \frac{55}{16} }{ \frac{605}{525} } \div \frac{7}{16}$

$\frac{ - \frac {1091}{400} }{ \frac{604}{525} } \div \frac{7}{16}$

$- \frac{22911}{9664} \times \frac{16}{7}$

$= - \frac{3273}{604}$

Sau

$= 5 \frac{253}{604}$

Sper că te-am ajutat!
