Question

Rezultatul calcului [1pe 3 ×(10-1pe 4 ) -3 2pe 5 ] ÷(2+4pe 5)

Answer 1

$[ \frac{1}{3}*(10- \frac{1}{4})-3* \frac{2}{5}]:(2+ \frac{4}{5})=[ \frac{1}{3}* \frac{39}{4}- \frac{6}{5}]: \frac{14}{5}=[ \frac{13}{4}- \frac{6}{5}]* \frac{5}{14}=$$\frac{41}{20}* \frac{5}{14}=\frac{41}{4}* \frac{1}{14}= \frac{41*1}{4*14}= \frac{41}{56}$
