问:把下列百分率化为最简分数 1.) 25% 2.) 75% 3.) 12.5% 4.) 1.05% 5.) 225% 答:1. 25% = 25/100 = 1/4 2.75% = 75/100 = 3/4 3. 12.5% = 125/1000 = 1/8 4.1.05% = 105/10000 = 21/2000 5. 225% = 225/100 = 2又1/4
25%=0.25=1/4 75%=0.75=3/4 12.5=125/1000=1/8 1.05=105/10000=21/2000 225%=225/100=2又1/4 study the 百分数的时候 要记左 1/4=25%=0.25 3/4=75%=0.75 1/2=50%=0.5 1/8=0.125=12.5% 3/8=0.375=37.5% 5/8=0.625=62.5% 7/8=0.875=87.5%
1.) 25% = 25/100 = 1/4 2.) 75% = 75/100 = 3/4 3.) 12.5% = 125/1000 = 1/8 4.) 1.05% = 105/10000 = 21/2000 5.) 225% = 225/100 = 2又1/4
1．1／4 2．3／4 3．1／8 4．21／2000 5．9／4
