What is the difference between 3/7 and 1/14

A 1/2

B 4/14

C 5/14

D 9/14

C. 5/14

You find the LCD. In this case it would be 14 since both 7 and 14 can go into 14. You have to multiply the top by the same number as the bottom. 2*7=14

2*3=6. You now have 6/14. 6-1=5

The denominator stays the same. 5/14
