Answer:
1/2
1/4
1/8
Explanation:
We can use fractions to convey an amount that is less than 1 (the whole).
In a fraction, the denominator (on bottom) represents the total amount of parts there are of something. The numerator (on top) represents how many parts of the whole we are looking at in a specific instance.
For the two children, sharing a cake, the cake is split into two parts, so the denominator is 2. The numerator is 1 because each child gets 1 piece.
For the four children, there are four available parts and each child gets 1 part.
For the eight children, there are eight available parts and each child gets 1 part.
