a) x : (-2,14) = (-3,12) : 1,2
=> x:(-2,14)= -2,6
=> x= -5,564
b) \(2\frac{2}{3}:x=2\frac{1}{12}:\left(-0,060\right)\)
=> \(\frac{8}{3}:x=\frac{-625}{18}\)
=> x= \(\frac{8}{3}:\frac{-625}{18}\)
=> x= \(\frac{-48}{625}\)
2,14kg = 0,214 yến
5,62 yến = 0,562 tạ
1,3 tạ = 130 kg
216,3 kg = 21,63 yến
1/2 kg > 160g
2,14 kg = 0,214 yen
5,62 yen = 0,562 ta
1,3 ta = 130 kg
216,3 kg = 21,63 yen
1 / 2 kg = ..?..160 g
a) \(\frac{1}{9}+3,25+5\frac{3}{16}+4\frac{1}{3}+2,8+0,5=\frac{1}{9}+\frac{13}{4}+\frac{83}{16}+\frac{13}{3}+\frac{14}{5}+\frac{1}{2}\)
\(=\frac{11651}{720}\)
B) \(2\frac{1}{3}+0,45+4,25+\frac{1}{81}+6\frac{8}{27}=\frac{7}{3}+\frac{9}{20}+\frac{17}{4}+\frac{1}{81}+\frac{170}{27}\)
\(=\frac{10807}{810}\)
C) \(1,25+2\frac{1}{4}+4\frac{2}{5}+0,3+2,14+4\frac{1}{8}=\frac{5}{4}+\frac{9}{4}+\frac{22}{5}+\frac{3}{10}+\frac{107}{50}+\frac{33}{8}\)
\(=\frac{2893}{200}\)

a: \(=\dfrac{1}{9}+\dfrac{13}{4}+5+\dfrac{3}{16}+4+\dfrac{1}{3}+\dfrac{14}{5}+\dfrac{1}{2}\)
\(=9+\dfrac{4}{9}+\dfrac{14}{5}+\dfrac{52}{16}+\dfrac{3}{16}+\dfrac{8}{18}\)
\(=9+\dfrac{146}{45}+\dfrac{63}{16}=\dfrac{11651}{720}\)
b: \(=\dfrac{7}{3}+\dfrac{9}{20}+\dfrac{85}{20}+\dfrac{1}{81}+6+\dfrac{8}{27}\)
\(=6+\dfrac{94}{20}+\dfrac{7\cdot27+1+8\cdot3}{81}\)
\(=6+\dfrac{94}{20}+\dfrac{214}{81}=\dfrac{10807}{810}\)
