1樓:黎祖南

簡便計算過程方法如下

解:5/6-4/5+1/6

=5/6+1/6-4/5

=1-4/5

=1/5

2樓:義明智

簡便計算

5/6-4/5+1/6

=5/6+1/6-4/5

=1-4/5

=1/5

3樓:陳長的路上

5/6-4/5+1/6

=5/6+1/6-4/5

=1-4/5

=1/5

4樓:匿名使用者

原式=5/6+1/6-4/5

=1-4/5

=1/5

2/5÷5/6×6/5,12÷(2/3+1/4)能簡便的簡便計算。。。。快點謝謝

5樓:匿名使用者

2/5÷5/6×6/5

=2/5÷(5/6×6/5)

=2/5

12÷(2/3+1/4)

=12÷2/3+12÷1/4

=18+48=66

7/8+1/6-5/12簡便計算,謝謝

6樓:我愛五指山

7/8+1/6-5/12

=7/8+(2/12-5/12)

=21/24-6/24

=5/8

【1又1/24-(3/8+1/6-3/4)×24】×2/5 請用簡便方法計算,謝謝大家,幫我解答

7樓:妙酒

【1又1/24-(3/8+1/6-3/4)×版24】×2/5=(1又權1/24-3/8x24-1/6x24+3/4x24)x2/5

=(1又1/24-9-4+18)x2/5

=(25/24+5)x2/5

=25/24x2/5+5x2/5

=5/12+2

=2又5/12
