If 0.75 : x : : 5 : 8, then x is equal to :Options :1.121.201.251.30

This is a question of proportion. In a proportion, the product of the extremes (the first and the last terms) equals the product of the means (the second and third terms).

So, we can set up the equation like this:

0.75 * 8 = 5 * x

Then, we solve for x:

6 = 5x

Finally, we divide both sides by 5 to isolate x:

x = 6 / 5 = 1.2

So, the answer is not in the options provided. There seems to be a mistake in the options.
