3/4 = 6/8
S is increased from 4 to 6: a multiple of 6/4 = 1.5 So P, which is directly proportional to S, increases from 18 to 18*1.5 = 27
r + s = 4 and 2r + 3s = 8 multiply the first equation by 2 giving 2r + 2s = 8 subtract this from the second equation giving s = 0 So r = 4 and s = 0.
G = 9, L = 1, O = 5, 6 or 7, P = 3, 4 or 5 and S = any unused digit...
1008 4's multiples 4 8.... 1000 1004 1008 1012 1016 1020 3's multiples 3 6.... 1002 1005 1008 1011 1014 1017 1008 divided by 4 equals 252 1008 divided by 3 equals 336

Assuming the sides of the triangle a=5, b=5 and c=6, the semiperimeter s=(5+5+6)/2=8. Height d=3 is not necessary if you use Heron´s formula for the area (A): A = [s(s-a)(s-b)(s-c)]1/2 = [8(8-5)(8-5)(8-6)]1/2 = [144]1/2 = 12
s = 4
62•4= 4•2=8 6•4=24 so add the two #'s and you get 248 8D

Use the four 4's in the following ways: 4 + 4 = 8 8/4 = 2 2 + 4 = 6. Therefore, ((4 + 4)/4) + 4 = 6
