I think it's the second one, 3 1/3
Divide 2 cakes by 2/3 serving:

7×20 and 7×2000 are similar. The amount of zeros are the dependent factor.
7×20= 140
7×2000= 14000
The base equation is 7×2=14
Any additions of zeroes in this formula will be added at the end result.
Ex.
7×2=14
7×20=140
7×200=1400
70×200=14000
700×200=140000
Medida do angulo central = medida do arco interceptado
