Question

what is the difference between 3/7 and 1/14
A 1/2
B 4/14
C 5/14
D 9/14

Answer 1

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
