The sign that will be put on the cake is -13/40 to indicate the shortage of frosting.
Number of cakes to frost = 15
Amount of frosting required = 4 7/8
In this case, since she used the frosting that she had but was still short of some frosting and a sign was made to represent this. Then, it'll be:
= 4 7/8 ÷ 15
= 39/8 × 1/15.
= 13/40
Therefore, the sign that will be put on the cake is -13/40.
