How do you decompose 17?

We could use a part–whole model to show how we can decompose or split up the number 17. The whole amount is 17. And we can split this up into 10 ones, which is worth 10, and seven ones, which is worth seven. 10 and seven go together to make 17.

What is an example of decomposing in mathematics?

In math, when you break a number apart, it’s called decomposing. To see this in action, try to think of all the different ways to make 7. The two parts you may have come up with that made 7 could have been 4 + 3, 2 + 5, 0 + 7, or 1 + 6. These different parts are decomposed numbers from 7.

How do you decompose 80?
