Answer :
Answer: 22
Step-by-step explanation:
From the question, we are given the information that of the balloons recently sold by party store, 4 were purple and 8 were other colors. This means that the fraction of those that was purple is:
= 4/(4+8)
= 4/12
= 1/3.
Therefore, if there are 66 balloons, the number expected to be purple will be:
= 1/3 × 66
= 22
There'll be 22 purple balloons
