1/6×34/5+17/6×28/5-1/6= =1/6×(34/5-6/5)+17/6×28/5= =1/6×28/5+17/6×28/5= =28/5×(1/6+17/6)= =84/5 .Mình xin hay nhất và 5 sao nha .Chúc bạn thi tốt nha Bình luận
`1/6 \times 34/5 + 17/6 \times 28/5 – 1/6 \times 6/5`
`= 1/6 \times ( 34/5 – 6/5 ) + 17/6 \times 28/5 `
`= 1/6 \times 28/5 + 17/6 \times 28/5 `
`= 28/5 \times ( 1/6 + 17/6 ) `
`= 28/5 \times 18/6 `
`= 84/5`
1/6×34/5+17/6×28/5-1/6=
=1/6×(34/5-6/5)+17/6×28/5=
=1/6×28/5+17/6×28/5=
=28/5×(1/6+17/6)=
=84/5
