Đáp án
-5/2
Giải thích các bước giải:
A = (6- 2/3 + 1/2 ) – ( 5 + 5/3 – 3/2 ) -( 3 – 7/3 + 5/2 )
A = 6-2/3+1/2-5-5/3+3/2-3+7/3-5/2
A= 6-5-3-2/3-5/3+7/3+1/2+3/2-5/2
A = (6-5-3)-(2/3+5/3-7/3)+(1/2+3/2-5/2)
A =-2-0+(-1/2)
A =-2+(-1/2)
A = -4/2+(-1/2)
A =-5/2
CHO MIK HAY NHẤT NHÉ
`A = (6- 2/3 + 1/2 ) – ( 5 + 5/3 – 3/2 ) -( 3 – 7/3 + 5/2 )`
`A = 6 – 2/3 + 1/2 – 5 – 5/3 + 3/2 – 3 + 7/3 – 5/2`
`A = ( 6 – 5 – 3 ) + ( -2/3 – 5/3 + 7/3 ) + ( 1/2 +3/2 -5/2 )`
`A = -2 + 0 – 1/2`
`A = -5/2`
