2 ) 10:2
3) 5:2
4 )30: 18
5) 24 :16

Answer 1

1) 60:36

2) 10:2

The ratio form can be written as
`(20)/(12)` and it is
`(5)/(3)`, 5:3 (ratio form)

1) 60:36

`(60)/(36)` =
`(5)/(3)`

=5:3 (yes)

2) 10:2

`(10)/(2)`=
`(5)/(1)`

= 5;1 (NO)

3) 5:2

`(5)/(2)`= 5:2 (NO)

4) 30:18

`(30)/(18)`=
`(5)/(3)`

= 5:3 (yes)

5) 24:16

`(24)/(16)`=
`(3)/(2)`

= 3:2 (NO)
