\(a)22.3-\left(110+7\right):326\)
\(=66-117:326\)
\(=66-\frac{117}{326}\)
\(=\frac{21399}{326}\)
\(b)1+2+3+.....+2019+2010\)
Ta tạm để số 2010 ra ngoài .
Số số hạng của tổng trên là :
( 2019 - 1 ) : 1 + 1 = 2019 ( sh )
Tổng trên là :
\(\left(2019+1\right)\times2019:2=2039190\)
\(\Rightarrow2039190+2010=2041200\)
\(c)64:4+2.52\)
\(=16+104\)
\(=120\)
\(d)2008.213+87.2008\)
\(=2008.\left(213+87\right)\)
\(=2008.300\)
\(=602400\)
\(e)12: \left\{390:\left[500-\left(125+35.7\right)\right]\right\}\)
\(=12:\left\{390:\left[500-370\right]\right\}\)
\(=12:\left\{390:130\right\}\)
\(=12:3=4\)
\(g)33.118-33.18\)
\(=3894-594\)
\(=3300\)
\(h)150-\left[102-\left(14-11\right).2\right]:9\)
\(=150-\left[102-6\right]:9\)
\(=150-96:9\)
\(=150-\frac{32}{33}\)
\(=\frac{4918}{33}\)
\(i)4.52-3\)
\(=208-3\)

\(=\frac{96}{64}+\frac{80}{64}+\frac{72}{64}+\frac{66}{64}+\frac{65}{64}-7\)
\(=\frac{96+80+72+66+64}{64}-7\)
\(=\frac{378}{64}-\frac{7}{1}\)
\(=\frac{189}{32}-\frac{224}{32}\)
