Question from Hana: hi my brother a 5th grade have a question. this is what it say "i have only one factor array, and i am between two numbers 12 and 16. what number am i?" |
Hi Hana,
Have a look at this question we received a while ago.
You will see that for the number 2 I have two arrays, one with two rows and one column and the other with one row and two columns. The person who wrote the question for your brother would say that the number 2 has only one factor array, it is 2 by 1. With this interpretation 4 has two factor arrays and 5 has one factor array.
Do you see now how to approach your brother's problem? Write back if you need more assistance,
Penny
