A survey of all beings on planet Dubble found that 12 beings preferred gespil juice to all other juices. If 40 were surveyed altogether, what percent of them preferred gespil juice?

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

(x) - (y) = (1 + 4i)
