1.问几道简单的六年级数学题目
1.石灰x，硫磺2x，水12x 25
x 2x 12x 25=400
x=25硫磺=2x=50水=325
2.设x天后存粮相等
32 9x=7 4x
x=5
3.取了x次
6x=4x 14
x=7
原有6x=42只棋子
4，设x辆车
60x 15=65(x-1)
x=16
人数=60x 15=975人
5.售出40,50元的票数为x张
30(200-2x) 40x 50x=7800
x=60张
售出40,50元的票数为60张，30元的为80张
6.设至少x1,x2票，
①13 x1=10 (18-x1)
②13 x2=7 (18-x2)
x1=7.5x2=6取交集=7
又因为不能同时存在2个中队长，所以甲同学要7 1=8票才能当选
