64=2*2*2*2*2*2=2⁶
B⁻³=1/64
1/B³=1/2⁶
B³=2⁶
B=∛2⁶=2⁶/³=2²=4

So whole ml's
30 mls
find what 30 is evenly divisble by 
factor 30
30=2 times 3 times 5
therefor
30 is divisble by 2,3,5,6,10,15
so he can divide the glass into 2 sevings which is 30/2=15 ml in each
servings    ml         fraction
2              15            15/30=1/2
3              10              10/30=1/3
5                6             6/30=1/5
6              5                5/30=1/6
10               3              3/30=1/10
15              2              2/30=1/15
