She could've cut the cake into 6 pieces so everyone could have an equal slice of cake or she could've cut it into 12 pieces and everyone could have 2 pieces each equally
hope this helps :)
It would be subtraction I think
Answer:
Sharon bought a necklace with 90% blue beads.
Step-by-step explanation:
We are given that Sharon's necklace has 80 beads. We are also given that of those 80 beads, 72 of them are blue.
Therefore, we can set up a ratio of blue beads to total beads in order to find out the relationship.

Then, using the fraction we receive as a result, we can convert this to a decimal.

After we complete this calculation, we can multiply our decimal by 100 in order to obtain the relationship in percentage form.

Of the 80 beads, 90% were blue beads.
Probably like ten maybe four
