Answer:
60,000, 80,000, 100,000, 90,000, 60,000
Explanation:
First you have to determine which position is the "ten thousands" position. Then look at the digit to its right: if it's 5 or more you round up, 4 or less you round down.
So let's start with the first number. The places are easier to see if you include the comma:
57,342
Do you know the places? They're like this:
ten thousands thousands , hundreds tens ones
So '5' is in the ten thousands place.
Now look to its right and you see '7'.
That's ≥ 5, so you round up.
What do you round up? The '5' in the ten thousands place.
So the '5' rounds up to a '6', and everything behind it goes to zero:
60,000
Others:
76,564 7 in ten thousands place, 6 to its right, so round up: 80,000
95,634 The 5 says you round up the 9: 100,000 Notice how there's essentially a '10' in the ten thousands place, so the number becomes one hundred thousand.
85,756 5 says round up 8: 90,000
63,256 3 says you round down, which means that the 6 stays a 6: 60,000
