展开全部
解:(-1/2+1/6-3/4+5/12)÷(-12)等于( 1/18 )
∵已知需求出(-1/2+1/6-3/4+5/12)÷(-12)等于多少
∴(-1/2+1/6-3/4+5/12)÷(-12)
= (-1/2 + 1/6 - 3/4 + 5/12)× (-1/12)
= (-12/24 + 4/24 - 18/24 + 10/24)× (-1/12)
= (-8/24 - 18/24 + 10/24)× (-1/12)
= (-26/24 + 10/24)× (-1/12)
= (-16/24)× (-1/12)
= (-1/2)× (-1/12)
= 1/18
答:(-1/2+1/6-3/4+5/12)÷(-12)等于1/18
