Question

计算（怎样简便就怎样算） (1)/(3)×(3)/(5)÷(1)/(3)×(3)/(5)=	(3)/(4)×6.7+4.3×0.75−75%=	((7)/(10)+(5)/(6)−(4)/(5))×30=
[1−((1)/(2)−(1)/(4))] ×(2)/(3)	(1)/(4)：(1)/(6)＝(1)/(8)：x	x+(1)/(4)x=60．

Answer 1

（1）(1)/(3)×(3)/(5)÷(1)/(3)×(3)/(5)，
=(1)/(3)÷(1)/(3)×(3)/(5)×(3)/(5)，
=(9)/(25)；

（2）(3)/(4)×6.7+4.3×0.75−75%
=0.75×6.7+4.3×0.75-0.75，
=（6.7+4.3-1）×0.75，
=10×0.75，
=7.5；

（3）((7)/(10)+(5)/(6)−(4)/(5))×30
=(7)/(10)×30+(5)/(6)×30-(4)/(5)×30，
=21+25-24，
=22；

（4）[1−((1)/(2)−(1)/(4))] ×(2)/(3)
=[1-（0.5-0.25）]×(2)/(3)，
=[1-0.25]×(2)/(3)，
=0.75×(2)/(3)，
=0.5；

（5）(1)/(4)：(1)/(6)＝(1)/(8)：x
         (1)/(4)x=(1)/(6)×(1)/(8)
      (1)/(4)x÷(1)/(4)=(1)/(6)×(1)/(8)÷(1)/(4)，
