osoriklove По действиям если, то:
$2: \frac{1}{2} (21 \frac{88}{95}+29 \frac{37}{38}-1 \frac{9}{10}-48 \frac{5}{16} )*1 \frac{1}{9}=$ $11,5 
$
1→ $21 \frac{88}{95}+29 \frac{37}{38}= \frac{2083}{95} + \frac{1139}{38}= \frac{4166}{190} + \frac{5695}{190}= \frac{9861}{190}=51,9$
2→ $51,9-1 \frac{9}{10}=51 \frac{9}{10}-1 \frac{9}{10}=50 \frac{9}{10}=50,9$
3→ $50 \frac{9}{10}-48 \frac{5}{16}= \frac{509}{10} - \frac{773}{16}= \frac{4072}{80} - \frac{3865}{80}= \frac{207}{80}$
4→ $2: \frac{1}{2}=2* \frac{2}{1} =4$
5→ $4* \frac{207}{80}= \frac{4*207}{80}= \frac{207}{20}$
6→ $\frac{207}{20}*1 \frac{1}{9}= \frac{207}{20}* \frac{10}{9}= \frac{207*10}{20*9}= \frac{23}{2}=11 \frac{1}{2}=11,5$
