Using proportions, it is found that:
a) 75% of the respondents believe the action is morally acceptable.
b) Supposing there are 217 million adults, 39.06 million believe that the action is morally wrong.
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
In item a, 75 out of 7 + 18 + 75 = 100 adults believe that the action is morally acceptable, hence the percentage is:
75/100 x 100% = 75%
75% of the respondents believe the action is morally acceptable.
In item b, we suppose that there are 217 million adults, hence the amount that believe the action is morally wrong is:
0.18 x 217 = 39.06.
Supposing there are 217 million adults, 39.06 million believe that the action is morally wrong.
