分数计算9/4-1/9+2/3
解题思路:需要先进行通分(最小公倍数),通分转换为公分母后将所有分子相加减后得出计算出来的分数,之后再化简为最简分数即可。
解题过程:
9/4-1/9+2/3
=9/4+(6/9-1/9)
=9/4+5/9
=81/36+20/36
=101/36
存疑请追问,满意请采纳
9/4-1/9+2/3
=9/4+(2/3-1/9)
=9/4+5/9
=81/36+20/36
=101/36
希望能帮到你!
9/4-1/9+2/3
=9/4-(1/9-2/3)
=9/4-(1/9-6/9)
=9/4-(-5/9)
=9/4+5/9
=81/36+20/36
=101/36
=2又29/36
