Question

(6-\(\frac{1}{4}-\frac{7}{9}\))-\(\left(\frac{2}{9}+\frac{3}{4}-4\right)\)=

Answer 1

\(\left(6-\frac{1}{4}-\frac{7}{9}\right)-\left(\frac{2}{9}+\frac{3}{4}-4\right)\)

\(=6-\frac{1}{4}-\frac{7}{9}-\frac{2}{9}+\frac{3}{4}+4\)

\(=\left(6+4\right)+\left(\frac{-1}{4}+\frac{3}{4}\right)+\left(\frac{-7}{9}+\frac{-2}{9}\right)\)

\(=10+\frac{1}{2}+\left(-1\right)\)

\(=10+0,5+\left(-1\right)\)

\(=9,5\)

Answer 2

\(\left(6-\frac{1}{4}-\frac{7}{9}\right)-\left(\frac{2}{9}+\frac{3}{4}-4\right)\)

\(=6-\frac{1}{4}-\frac{7}{9}-\frac{2}{9}-\frac{3}{4}+4\)

\(=10-1-1\)

\(=8\)

Answer 3

\(=6-\frac{1}{4}-\frac{7}{9}-\frac{2}{9}-\frac{3}{4}+4\)

\(=\left(6+4\right)-\left(\frac{1}{4}+\frac{3}{4}\right)-\left(\frac{7}{9}+\frac{2}{9}\right)\)

\(=10-1-1\\ =8\)

Answer 4

Sorry mik lôn 1 chút

Mik sửa lại nha!!!

\(=6-\frac{1}{4}-\frac{7}{9}-\frac{2}{9}-\frac{3}{4}+4\)

\(=\left(6+4\right)+\left(\frac{-1}{4}+\frac{-3}{4}\right)+\left(\frac{-7}{9}+\frac{-2}{9}\right)\)

\(=10+\left(-1\right)+\left(-1\right)\)

\(=8\)
