tính nhanh 18.(19191919/21212121 + 88888/99999)
18 x (19191919/21212121 + 88888/99999)=?
\(=18x\frac{19x1010101}{21x1010101}+\frac{8x11111}{9x11111}=18x\frac{19}{21}+\frac{8}{9}\)
sao khong có kết quả hả bạn
\(18\cdot\left(\frac{19191919}{21212121}+\frac{88888}{99999}\right)\)
\(=18\cdot\left(\frac{19}{21}+\frac{8}{9}\right)\)
\(=18\cdot\frac{113}{63}\)
\(=\frac{678}{21}\approx32,286\)
2 . Tính giá trị biểu thức :
9 x ( 262626/272727+88888/99999)
9 x ( 262626/272727 + 88888/99999 )
= 9 x ( 26/27 + 8/9 )
= 9 x 50/27
= 50/3
