5:4
Ratios can be written either like this 4/5 or 4:5 both mean 4 out of 5
2/5, 4/10, 6/15, 8/20
no they are not
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.
No
It could be 8 and 10
yes
Yes
It could be that: 5 to 20 is equivalent 1 to 4
10 over 24 and 15 over 36
There are infinitely many equivalent ratios. 320 over 400 is one. 4 over 5 another.
Equivalent ratios to 4/5 can be several such as 8/10 or 16/20.
