Question

What is the sum of 234 and 87 rounded to the nearest ten?

Answer 1

320

Explanation:

Add `234` and `87` together.

`234+87`

`=321`

To round `3color(red)2color(blue)1` to the nearest ten, start by referring to the number, `color(red)2`, in the tens place. Then look at the number after it, `color(blue)1`. Since `color(blue)1` is less than `5`, change the `color(blue)1` to a `0`.

Thus:

`321rArr320`
