What is the ratio forms a proportion with 16/204/1032/508/124/5

D) 4/5

Explanation:

There are a few ways to see how this is the answer.

The first is to notice how 16/20 = 0.80 when using long division or a calculator. At the same time, 4/5 = 0.80 as well. So that means 16/20 = 4/5.

Another way to see how this works is to multiply top and bottom of 4/5 by 4. So we have 4*4 = 16 as the new numerator and 5*4 = 20 as the new denominator. Going in reverse, you can divide each piece of 16/20 by the GCF 4 to reduce this fraction into 4/5.

Finally, we can equate the two fractions and cross multiply

16/20 = 4/5

16*5 = 20*4

80 = 80

Both sides are the same value, so that confirms the original equation is true as well.

ik how do do this just give me a few minutes and i will give it to

(hint): the answer is in the question.
