Question

Round 3,153,007 to the nearest 100,000

Answer 1

3,200,000. 5 rounds up, so 1=2 , and you change every number after the 2 to 0's

Answer 2

Answer- 3,200,000
To round 3,153,007 you want to look at the 3 and the 5. The rule is if the second number is 5 or greater you round up. So the 1 bumps up to a 2 and the rest of the numbers turn to 0. If the second number is lower then 5 it stays the same. So if it were a 4 the answer would be 3,100,100
