I may not help. But i believe it is something to do with the lowest common multiple between those 2 being 60
Answer:
Step-by-step explanation:
Find the value of the left hand side (LHS)
LHS = 1/4 // 5/6
LHS = 1/4 * 6/5
LHS = 6/20
LHS = 3/10
Now what will make 3/10 on the right?
B: 1/4 * 6/5 = 6/20 = 3/10
a = 4
b = 6
c = 5
Answer:
5
Step-by-step explanation:
Distance formula is 
now you plug in your numbers. 



=5

20 divided by 12 would be 12 and 4 for the greatest common factor so in simplistic form you would get 1 2/3. I hope I got the answer correct.....
