Question

There were n balloons at the beginning of the party. By the end of the party, 5 of them had popped. Using n, write an expression for the number of balloons that were left

Answer 1

The expression for the number of balloons that were left is
`n-5`.

Explanation:

There were n balloons at the beginning of the party.

By the end of the party, 5 of them had popped.

Let the remaining balloons be represented by x

So, x = total balloons minus 5

This gives:
`x=n-5`

Therefore, the expression for the number of balloons that were left is
`n-5`.
