Just divide the distance of each to point P by 2.
C would be 1 unit above and 2 units to the right of P.
D would be 1 unit below and 2 units to the right of P.
And so on...
Hope this helps
12 = 2*2*3
10 = 5*2
LCM = 5*3*2*2
= 15*4=60
the least common multiple is 60
The answer would be 30% , 3% would only be correct if he gave 0.3/10
