Question

a) \(\frac{14}{21}+1-|\frac{1}{3}-1|\)

b) \(\frac{1}{3}-|\frac{-1}{4}+\frac{5}{6}|-|\frac{-7}{12}|\)

c)  \(|\frac{-5}{6}+\frac{1}{2}|-\frac{1}{3}+|\frac{-5}{12}|\)

d) \(\frac{-10}{6}-\frac{4}{-8}|\frac{-3}{4}+\frac{5}{-2}|\)

e)  \(|\frac{-5}{2}|-|\frac{-4}{28}+1|-\frac{-3}{14}\)

g)  \(\frac{5}{7}-|\frac{-4}{28}+\frac{1}{2}|-|\frac{-3}{14}|\)

Các bạn giúp mik bài này nhé. Càm ơn nhiều

Answer 1

a) \(\frac{14}{21}+1-\left|\frac{1}{3}-1\right|\)

\(=\frac{2}{3}+1-\frac{2}{3}\)

\(=1+\left(\frac{2}{3}-\frac{1}{3}\right)\)

\(=1\)

b) \(\frac{1}{3}-\left|\frac{-1}{4}+\frac{5}{6}\right|-\left|\frac{-7}{12}\right|\)

\(=\frac{1}{3}-\frac{7}{12}-\frac{7}{12}\)

\(=-\frac{5}{6}\)

Answer 2

Các câu khác làm tương tự thôi :))

Answer 3

\(\frac{1}{3}-|\frac{-1}{4}+\frac{5}{6}|-|\frac{-7}{12}|\)

\(=\frac{2}{3}+1-\frac{2}{3}\)

\(=1+(\frac{2}{3}-\frac{2}{3})\)

\(=1\)
