\(A=(1\frac{1}{5}+\frac{17}{24}+\frac{29}{32}+\frac{1}{4}+\frac{7}{24}+\frac{3}{32})\div4\)
\(A=\left\{1\frac{1}{5}+\frac{1}{4}+(\frac{17}{24}+\frac{7}{24})+(\frac{29}{32}+\frac{3}{32})\right\}\div4\)
\(A=\left\{\frac{29}{20}+1+1\right\}\div4\)
\(A=\frac{69}{20}\div4\)
\(A=\frac{69}{80}=0,8625\)
a=(6/5+17/24+29/32+1/4+7/24+3/32):4
a=[6/5+(17/24+7/24)+(29/32+3/32+1/4)]:4
a=[6/5+1+1+1/4):4
a=[24/20+20/20+20/20+5/20]:4
a=[44/20+25/20]:4
a=69/20:4
a=69/80
a=
a=đấy là thưa nha
Bài làm
\(A=\left(1\frac{1}{5}+\frac{17}{24}+\frac{29}{32}+\frac{1}{4}+\frac{7}{24}+\frac{3}{32}\right):4\)
\(A=\left(\frac{6}{5}+\frac{17}{24}+\frac{29}{32}+\frac{1}{4}+\frac{7}{24}+\frac{3}{32}\right):4\)
\(A=\left(\frac{1}{4}+\frac{6}{5}+\frac{24}{24}+\frac{32}{32}\right):4\)
\(A=\left(\frac{5}{20}+\frac{24}{20}+1+1\right):4\)
\(A=\left(\frac{29}{20}+1+1\right):4\)
\(A=\left(\frac{29}{20}+\frac{20}{20}+\frac{20}{20}\right):4\)
\(A=\frac{69}{20}:4\)
\(A=\frac{69}{20}.\frac{1}{4}\)
\(A=\frac{69}{80}\)
Vậy \(A=\frac{69}{80}\)
