27 students are learning to make balloon animals. there are 172 balloons to be shared equally among the students
a. how many balloons are left over after sharing them equally.
b. if each student needs 7 balloons, how many more balloon are needed? explain

A.) .4 of a balloon is left
To Check:
what I did was divide 172 by 27 and it is 6.37 rounded to 6 is an equal number so I kept it and .4 will be left over after sharing equally.

B.) 17 more balloons are needs
To Check:
what I was multiply 27 by 7 because each student needs seven balloons and I got 189 after that I subtracted 172 from 189 (189-172=17)
to see how many more balloons are needed.

Iam unsure about what the proof is, therefore as much as wish to i can not.
