我要15道简单的百分数解方程,比如这样的：80%x=260.还要20道百分数解方程,比如这样的：85%x+25=372

60%X=6 12%x=4。8 75%X=15 120%x=81。6 20%x+5。6=9。4 52－50%x ＝15 91%x ＝13 X+8。3=10。7 15%x ＝3 40%x－8＝16 30%x+9=27 18%x=270 12%x=30070%x+5。3=7。4 30%x÷5=4。8 30%x+25=85 1。4×8-20%x=6 60%x-12。8×3=0。06 410-40%x=170 X-0。25= 25% 25%X =30% 4+70%X=102 X-37。5%X=400 X+X50%=42 X+25%X=105 70%X+ 20%X = 3。6 X×60%=20×25% X- 15%X = 68 X＋37。5%X＝121 2/3X÷25%＝12 x- 80%x = 22 X＋25%X=90 X-12。5%X=8 80%x -4= 21 X＋25%X=90 70%X+ 20%X = 3。6 25%+ 10X = 80% X - 15%X = 68 25%X+ 10X = 4/5
