Question

[Hoàng Tử Gió]

Tính 67/43+106/79+52/79+19/43

Answer 1

[Nguyễn Hưng Phát]

\(\frac{67}{43}+\frac{106}{79}+\frac{52}{79}+\frac{19}{43}\)

\(=\left(\frac{67}{43}+\frac{19}{43}\right)+\left(\frac{106}{79}+\frac{52}{79}\right)\)

\(=2+2\)

\(=4\)

Answer 2

[Nguyễn Văn Trường]

\(Ta\) \(có\)

\(\frac{67}{43}+\frac{106}{79}+\frac{52}{79}+\frac{19}{43}\)

\(=\left(\frac{67}{43}+\frac{19}{43}\right)+\left(\frac{106}{79}+\frac{52}{79}\right)\)

\(=\frac{86}{43}+\frac{158}{79}\)

\(=\frac{6794}{3397}+\frac{6794}{3397}\)

\(=\frac{13588}{10094}=\frac{6794}{5047}\)
