If you mean 5/20 then it is equivalent to 1/4 in its simplest form
10 and 4 15 and 6
2 to 4, 4 to 8, 5 to 10
They are: 4 to 10, 6 to 15 and 8 to 20
no they are not
Equivalent ratios to 4/5 can be several such as 8/10 or 16/20.
It could be that: 5 to 20 is equivalent 1 to 4
No
To compare we have to calculate the ratios in simplest form. The ratios of 6 /8 =3/4.and 8/10 =4/5 . and we can say 4/5 is not equal to 3/4.
