解:8/3÷((5/6-1/2)×15/4)等于( 32/15 )
∵已知需求出8/3÷((5/6-1/2)×15/4)等于多少
∴8/3 ÷ [(5/6 - 1/2)× 15/4]
= 8/3 ÷ [(10/12 - 6/12)× 15/4]
= 8/3 ÷ (4/12 × 15/4)
= 8/3 ÷ 5/4
= 8/3 × 4/5
= (8×4)/(3×5)
= 32/15
答:8/3÷((5/6-1/2)×15/4)等于32/15
8/3÷[(5/6-1/2)×15/4]
=8/3÷[(5/6-3/6)×15/4]
=8/3÷[2/6×15/4]
=8/3÷1/3÷15/4
=8/3x3x4/15
=8x4/15
=32/15
=2又2/15
根据题意,解答如下
原式=8/3÷(2/6*15/4)
=8/3÷(1/2*5/2)
=8/3÷5/4
=8/3*4/5
=32/15
=2又2/15
