求比值:0.25:3,0.05:3,2.45:1.4,1.25:0.25
求比值:0.25:3,0.05:3,2.45:1.4,1.25:0.25
求比值:0.25:3,0.05:3,2.45:1.4,1.25:0.25
求比值:
0.25:3 = 1/4 ×1/3 = 1/12
0.05:3,= 1/20 ÷3 = 1/60
2.45:1.4 = 2.45 ÷1.4 = 1.75
1.25:0.25 = 1.25 ÷0.25 = 5
0.25:3=1/4×1/3=1/12
0.05:3=1/20×1/3=1/60
2.45:1.4=245/140=1.75
1.25:0.25=125/25=5
