Question

sa se calculeze [2.5 + 1/2 x (1/4+1,(3) : 0,(6) )] : 3x5/8

Answer 1

$[2.5+ \frac{1}{2}*( \frac{1}{4}+1.3:0.6)]:3* \frac{5}{8}=[ \frac{5}{2} + \frac{1}{2}*( \frac{1}{4}+ \frac{13}{10} : \frac{3}{5} )]* \frac{1}{3} * \frac{5}{8}=$$[ \frac{5}{2} + \frac{1}{2}*( \frac{1}{4}+ \frac{13}{10} * \frac{5}{3} )]* \frac{1}{3} * \frac{5}{8}=[ \frac{5}{2} + \frac{1}{2}*( \frac{1}{4}+ \frac{13}{2} * \frac{1}{3} )]* \frac{1}{3} * \frac{5}{8}=$$[ \frac{5}{2} + \frac{1}{2}*( \frac{1}{4}+ \frac{13}{6} )]* \frac{1}{3} * \frac{5}{8}=[ \frac{5}{2} + \frac{1}{2}*\frac{29}{12}]* \frac{1}{3} * \frac{5}{8}=[ \frac{5}{2} +\frac{29}{24}]* \frac{1}{3} * \frac{5}{8}=$$\frac{89}{24}* \frac{1}{3} * \frac{5}{8}= \frac{89*1*5}{24*3*8}= \frac{445}{576}$
