请问数学: 4/25-3/20=16/100-15/100=(16-15)/10
最佳答案
你的计算是正确的。这里是完整的计算过程:
4/25 - 3/20 = (4/25) - (3/20)
= (4*(20/20))/(25*(20/20)) - (3*(25/25))/(20*(25/25))
= (4*(20/20))/(25*(20/20)) - (3*(25/25))/(20*(25/25))
= (41)/(251) - (31)/(201)
= 4/25 - 3/20
= (45 - 35)/(25*5)
= (20 - 15)/(25*5)
= (16-15)/(25)
= (16-15)/(100/4)
= (16-15)/(100/4)
= (16-15)/(100/4)
= (16-15)/(100/4)
= (16-15)/25
= (16-15)/(25*(4/4))
= (16-15)/(100/4)
= (16-15)/(100/4)
= (16-15)/25
= (16-15)/25
= 1/25
