Question

\(8\frac{2}{7}-\left(1\frac{1}{6}+25\%\right)\)

\(4\frac{3}{4}+\left(-0,37\right)+\left(-1,28\right)+\left(-2,5\right)+3\frac{1}{12}\)

(giải giúp mình với)

Answer 1

\(8\frac{2}{7}-\left(1\frac{1}{6}+25\%\right)=\frac{58}{7}-\left(\frac{7}{6}+\frac{1}{4}\right)=\frac{58}{7}-\frac{17}{12}=\frac{577}{84}\)

\(4\frac{3}{4}+\left(-0,37\right)+\left(-1,28\right)+\left(-2,5\right)+3\frac{1}{12}\)

\(=\frac{19}{4}+\left(-\frac{83}{20}\right)+\frac{37}{12}=\frac{3}{5}+\frac{37}{12}=\frac{221}{60}\)

Answer 2

\(8\frac{2}{7}-\left(1\frac{1}{6}+25\%\right)=\frac{58}{7}-\left(\frac{7}{6}+\frac{1}{4}\right)=\frac{58}{7}-\frac{17}{12}=\frac{577}{84}\)

Answer 3

\(8\frac{2}{7}-\left(1\frac{1}{6}+25\%\right)\)

\(=\frac{58}{7}-\left(\frac{7}{6}+\frac{1}{4}\right)\)

\(=\frac{58}{7}-\frac{17}{12}\)

\(=\frac{577}{84}\)

Answer 4

\(8\frac{2}{7}\)- \(\left(1\frac{1}{6}+25\%\right)\)

= \(\frac{58}{7}\)- \(\left(\frac{7}{6}+25\%\right)\)

= \(\frac{58}{7}\)-  \(\frac{14}{3}\)

= \(\frac{76}{21}\)

b) \(4\frac{3}{4}\)+ ( -0,37) + (-1,28) + (-2,5)+ \(3\frac{1}{12}\)

= 4,75 + (-0,37) + (-1,28)+(-2,5)+\(\frac{37}{12}\)

= 3/5 + 37/12

= 221/60
