The browser used for posting questions on this site is pathetic: it is incapable of accepting most mathematical notation and so reading and interpreting the questions requires a degree of guesswork. It is, therefore, difficult to be certain.
If your question was about 2:4 and 8:16 then the answer is YES.
Two ratios are equivalent if their simplest forms are the same.
34 x 24 = 816
It is 3 to 5 in its simplest form
They are: 30/14 and 45/21
To find 34 of 24, you can multiply 34 by 24. The result is 816. So, 34 of 24 equals 816.
LCM: 816
They are in exponents: 24*3*17 = 816
24 x 3 x 17 = 816
Multiply both numbers by the same number (not by zero), and you get an equivalent ratio.
It is: 4/24 = 1/6 in its lowest terms
816 = 24 x 31 x 171
It is: 24*3*17 = 816 2^4 x 3 x 17
