Question

Which ratio is different from the other three 2/5 610 8/20 12:30

Answer 1

When we make decimals of all the fractions, we would get the following:


`(2)/(5) = 0.4`

`(6)/(10) = 0.6`

`(8)/(20) = 0.4`

`(12)/(30) = 0.4`

As you can see, all the numbers equal 0.4, with the exception of 6/10. Hence, the number with the other ratio is 6/10.
