How do i round 3,176 to the nearest thousand
Answers
Here is the rule: 4 and below let it go (round down), 5 and above give it a shove (round up) Look to the place after the thousandths in the number 3,176 (the 1) Since it is below 5, you would round down to 3,000
Well you would look at the 176 in 3,176. Since it is less then half (500) you would round it down. So 3,176 rounded to the nearest thousand would be 3,000
