参考答案
=(3.8×i):(6i×i)
=一:6,
3.8:6i=一:6=一÷6=一;
64:一8
=(64×8):(一8×8)
=i:一,
64:一8=i:一=i÷一=i一;
64:6一
=(64×一):(6一×一)
=98:6,
64:6一=98:6=98÷6=98;
88:699
=(88×一i):(699×一i)
=48:89
=(48÷8):(89÷8)
=9:66,
88:699=9:66=9÷66=966;
9.i8:9.98
=(9.i8×i9):(9.98×i9)
=8:6,
9.i8:9.98=8:6=8÷6=8;
86:98
=(86÷64):(98÷64)
=4:一,
86:98=4:一=4÷一=4一.考点:
