You can have as many correct ratio as 77:24.5 since no common factor exists for the two, However, if you divide the two with the same number, the result is still a ratio with terms lower than the original. Example, divide them by 5, we get
15.4 : 4.9. This ratio is still the same as the original. For check, we can use the cross product
77 : 24.5 =? 15.4 : 4.9
77 (4.9) =? 24.5(15.4)
.377.3=? 377.3 ok!

a ratio is simply a fraction.
Flip the ratio (because it doesn't matter where the numbers are in the ratio, just how you qualify them)-- 24.5/77 and reduce the fraction.

77 : 24.5
= 7(11) : 7(3.5)
= 11 : 3.5
= 2(11) : 2(3.5)
= 22 : 7, i.e. whole numbers and no common factor.
