Write 5 names for 15.?

Question

That is the statement in my daughters math book "Everyday Mathematics: Student Math Journal 1." While it seems to want names, I think it wants something like the following:

5+10

3+3+3+3+3

12+3

This is all the book gives, and I do not see anything similar. Any ideas?

Answer 1

Maybe spelled out--Ten+five=fifteen

Answer 2

Well the only names I can think of are 15 and fifteen. But I think you're right on what the book probably wants. What I can think of is:

20-5

13+2

14+1

17-2

16-1

This is all I can think of...Good luck!

Answer 3

5+10

3+3+3+3+3

12+3

7+3+5

6+6+3
