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.
Equivalent ratios to 4/5 can be several such as 8/10 or 16/20.
It could be 8 and 10
2 to 4, 4 to 8, 5 to 10
10 and 4 15 and 6
4 to 10 6 to 15 8 to 20 10 to 25
3:2 four common ratios are... 6:4 9:6 12:8 15:10
2/3, 4/6
They are: 2 to 5, 6 to 15 and 8 to 20
2 to 5
5 to 1 15 to 3 20 to 4
5:4 = 10:8 = 20:16
