五年级分数解方程题

Answer 1

3.8+4.29+2.71+6.2 12.5—0.78—3.22 12.8×99+12.8

1.25×3.2×2.5 12.6×101—12.6 38.5÷2.5÷0.4

6.7×10.1 6.5×101 4.85×98

1.2×2.5+0.8×2.5 28×17.5—28×7.5 4.8×12.5

5X+7=42 16+8X=40 4X—3×9=29

2(X—2.6)=8 5(X+1.5)=17.5 (X—3)÷2=7.5

5.4X+X=12.8 X—0.36X=16 3.6X—X=3.25

4-X－5/7 = 1 6X－0.8 = 11.2 0.5+4.5x=45.5
