Ребята помогите решить пожалйста !

1)
$4,625- \frac{13}{18} * \frac{9}{26} =4,625- \frac{1}{4} =4,375$
$4,375/ \frac{9}{4} = \frac{35}{8} * \frac{4}{9} = \frac{35}{18}$
$\frac{2,5}{1,25} = 2$
$2/6,75= \frac{8}{27}$
$\frac{35}{18}+\frac{8}{27} = \frac{121}{54}$
$\frac{121}{54}* \frac{68}{121} = \frac{34}{27}$ - числитель

$\frac{1}{2}-0,375 = \frac{1}{8}$
$\frac{1}{8*0,125} =1$
$\frac{5}{6} - \frac{7}{12} = \frac{1}{4}$
$0,358-1,4796/13,7= \frac{1}{4}$
$\frac{1}{4} * 4=1$
$1+1=2$ - знаменатель

$\frac{34}{27*2}=\frac{17}{27}$

2)

$3,75:1,5=2,5$
$1,5:3,75=0,4$
$0,4*2,5=1$
$\frac{8}{7} - \frac{23}{49} = \frac{33}{49}$
$\frac{33}{49}* \frac{147}{22} =4,5$
$2,5+1+4,5=8$ - числитель

$2* \frac{5}{16} = \frac{5}{8}$
$\frac{13}{4} * \frac{1}{13} = \frac{1}{4}$
$\frac{1}{4} * \frac{3}{2} = \frac{3}{8}$
$\frac{41}{18} - \frac{17}{36} = \frac{65}{36}$
$\frac{65}{36}*\frac{18}{65}= \frac{1}{2}$
$\frac{5}{8}+\frac{3}{8}-\frac{1}{2}=\frac{1}{2}$ - знаменатель

$\frac{8}{0,5}=16$
