Question

What is the algebraic expression for half a number when the number is 10?

Answer 1

`x/2` for half of any number `x`; `10/2=5` when `x=10`

Explanation:

If our number is `x`, half of that number would be

`x/2`, where we are just dividing the number by `2`.

In our instance, our number, or `x`, is `10`, thus we have:

`10/2`, which simplifies to `5`
