Answer:
1/2
Explanation:
Factor both the numerator and denominator down to prime factors:
500 = 22 * 53
1,000 = 23 * 53
Calculate the greatest common factor, GCF (also called greatest common divisor, GCD), by taking all the common prime factors of the numerator and denominator, by the lowest exponents:
gcd (22 * 53; 23 * 53) = 22 * 53
Divide both the numerator and denominator by their greatest common factor, GCF (also called the greatest common divisor, GCD):
500/1,000 =
(22 * 53)/(23 * 53) =
((22 * 53) ÷ (22 * 53)) / ((23 * 53) ÷ (22 * 53)) =
1/2
Rewrite result:
1 ÷ 2 = 0.5 as a decimal number.
Hope this helps!!
