=\(\dfrac{3}{8}\)+\(\dfrac{3}{4}\)=\(\dfrac{3}{8}\)+\(\dfrac{6}{8}\)=\(\dfrac{9}{8}\)
\(\frac{373737-10101}{818181-30303}=\frac{363636}{787878}=\frac{36}{78}\)
\(\frac{474}{2054}=\frac{3}{13}\)
Ta có \(\frac{3}{13}=\frac{18}{78}\)
\(\Rightarrow\frac{18}{78}< \frac{36}{78}\)
\(\frac{373737-10101}{818181-30303}\)
=\(\frac{37.10101-10101}{81.10101-10101.3}\)
=\(\frac{10101.\left(37-1\right)}{10101.\left(81-3\right)}\)
=\(\frac{36}{78}\)
=\(\frac{6.6}{6.13}\)
=\(\frac{6}{13}\)
hk tốt nha bn
\(\frac{30303}{80808}+\frac{303030}{484848}=1\)
Hk tốt
\(\frac{30303}{80808}+\frac{303030}{484848}\)
\(=\frac{3}{8}+\frac{5}{8}\)
\(=\frac{8}{8}\)
\(=1\)
\(\frac{30303}{80808}+\frac{303030}{484848}\)
\(\frac{30303}{80808}=\frac{30303:10101}{80808:10101}=\frac{3}{8}\)
\(\frac{303030}{484848}=\frac{303030:60606}{484848:60606}=\frac{5}{8}\)
\(\frac{3}{8}+\frac{5}{8}=\frac{3+5}{8}=\frac{8}{8}=1\)
tk mk nha
hihi yêu mọi người nhiều lắm ạ !!!!
\(A=\left(9+\frac{30303}{80808}+7+\frac{303030}{484848}\right)+4,03\)
\(A=\left(9+\frac{3\times10101}{8\times10101}+7+\frac{30\times10101}{48\times10101}\right)+4,03\)
\(A=\left(9+\frac{3}{8}+7+\frac{5}{8}\right)+4,03\)
\(A=\left(9+7+\frac{3}{8}+\frac{5}{8}\right)+4,03\)
\(A=\left(16+1\right)+4,03\)
\(A=17+4,03=21,03\)
\(\frac{30303}{80808}=\frac{3\times10101}{8\times10101}=\frac{3}{8}\)
