So the ten thousands in 7,433,654 in this case would be 33,654.
So, you just want to round that to the nearest ten thousand.
(10,000, 20,000, 30,000, 40,000, etc.)
So we want to see which of those 33,654 is closest to.
In this case it would be closest to 30,000, as it is only 3,654 away from it.
And then we can just add it back in the number.
7,430,000 would be your answer.
