Given the problem:
263.76 to the nearest whole number.
When rounding, you’re always going to look back a place. If the number is greater than 5, round up. If it’s less than 5, round down. And if it’s 5, round up or down, depending on the problem and your teacher’s instructions. I usually round up.
So in this case, we’re going to look at 7, the fourth number from the left. 7 is the first number after the decimal point. We’re looking at 7 because we’re rounding the number to the nearest WHOLE NUMBER. So no decimals. Now is 7 greater or less than 5? Greater! You round up.
3 becomes 4.
Your answer is 264.
Hope this helped!
