75 - 18.5 = 56.5
the number is 56 1/2 or 56.5
You do 9x27=243 then take 2x31=62 add 243+62=305 then take 305 and subtract it from 28 305-28=277
so if i did it right you should get n=277
8 are left handed bc 20% of its 40 is 0.2×40 =8
6, 12 18 24 30 36 42 48 54 60...
12, 24 36 48 60...
15, 30 45 60...
Voila. 60 shows up in all three. Its the first one to show up, hence lcm (least common multiple)
1+ When the percent goes to the goku
