Question

3.84:2.4=x:1/4 x:0.75=20.25:1/8 3.6:4/3=1.8:x x:0.75=2:1.25

Answer 1

1、3.84:2.4=x:1/4

2.4x=3.84*1/4

x=0.4

2、 x:0.75=20.25:1/8

x:0.75=20.25*8

x=20.25*8*3/4

=121.5

3、3.6:4/3=1.8:x

3.6x=1.8*4/3

x=3/8

4、x:0.75=2:1.25

1.25x=0.75*2

x=1.5/1.25=6/5

5、2/3:x=2/15:3/5

2/15x=3/5*2/3

x=3

6、28:42=x:0.8

42x=28*0.8
