Question

Can u pls help me with this question ​

Answer 1

Explanation:

1).
`(6)/(9)=(2)/(3)`

= 2 : 3

2). 6 : 4 =
`(6)/(4)`

=
`(3)/(2)`

6 : 4 = 3 : 2

3).
`(15)/(45)=(1)/(3)`

= 1 : 3

4). 12 : 8 =
`(12)/(8)`

=
`(3)/(2)`

= 3 : 2

And
`(18)/(12)=(3)/(2)` = 3:2

Therefore, 12 : 8 =
`(18)/(12)`

5).
`(21)/(12)=(7)/(4)`

= 7 : 4

6). 4 : 10 =
`(4)/(10)`

=
`(2)/(5)`

Therefore, equivalent ratios are,

a). 2 : 3 =
`(6)/(9)`

b). 3 : 2 = 6 to 4

c).
`(15)/(45)` = 1 : 3

d). 18 to 12 = 12 to 8

e).
`7:4=(21)/(12)`

f).
`(2)/(5)=4:10`
