$270 , 000$

Explanation:

When you round to the nearest ten thousand, your answer will be a multiple of ten thousand.

Identify the ten thousand place holder it is the fifth digit from the right.

The number will be color(red)(??)0,000

But before you just discard the other digits and replace them with $0$s, you need to decide whether you will round up or down.

Look at the digit in the thousands place color(red)(??)color(blue)(0),000 - If it is $5$ or more, round up, if it is $4$ or less, the ten thousand value stays the same.

In this case we have $\textcolor{red}{26} \textcolor{b l u e}{5} , 427$

The thousands place value is $\textcolor{b l u e}{5}$, so the $\textcolor{red}{6}$ will become $\textcolor{red}{7}$

The digits which follow are all $0$

$\textcolor{red}{27} \textcolor{b l u e}{0} , 000$

If the number had been: $\textcolor{red}{26} \textcolor{b l u e}{3} , 427$, then the rounded value would be

$\textcolor{red}{26} \textcolor{b l u e}{0} , 000$
