Answer: 3/8
Step-by-step explanation: To write the fraction 6/16 in lowest terms, we divide the numerator and the denominator by the greatest common factor of 6 and 16.
Since the factors of 6 are 1, 2, 3, and 6 and the factors of 16 are 1, 2, 4, 8, and 16, the greatest common factor of 6 and 16 is 2.
So we divide the numerator and the denominator of 6/16 by 2.
6 divided by 2 is 3 and 16 divided by 2 is 8 so 6/16 written in lowest terms is 3/8.
