❄ Hi there,
let us revise the rounding rules and then, get down to rounding the number.

- If the number you need to round is followed by a number from 0 to 4, you round down.
- If the number you need to round is followed by a number that's 5 or more, you round up.
Now we can start the rounding process.

Looking at the fourth number, we notice that it's less than 5.
∴ we need to round down ↡
