Question

In the United States, about 1% of all births are multiple births (2 or more babies at one time). One hospital averages 12 sets of twins out of 1,000 births. Choose the answer that expresses this ratio as a fraction in lowest terms.

Answer 1

The answer would be 12/1000 but since it must be simplified
divide both sides of the fraction by the GCD which is 4 in this case
and the smallest possible fraction you recieve is 3/250 or 1 in every 83.33
your answer is 3/250
