Answer:
Step-by-step explanation:
Given, A pizza is to be cut into halves.
Since half is represented by .
So each piece is now of the original.
if each of these halves is to be cut into sevenths, then the fraction of final pieces would be: or we can say each half is divides into 7 pieces since there are two halves, so there will be 2 x 7 = 14 peices.
And the fraction of the pizza is each of the final pieces = .
