Question

describe how to round 678 to the nearest hundred

Answer 1

The answer is 700. First, find the hundreds place, then look at the digit right of that number, see if it's greater than 5, if so, round up, if no don't do anything. So 7 is greater than 5 so we change 6 to 7. Which is 700

Answer 2

Rounding up becomes:

678 ---> 700

the number after 6 (digit hundreds) is 7 (digit tens) so that number 6 is rounded up (adds 1) to 7 and the right side becomes 0

Further explanation

There are general rules used in rounding numbers

• 1. Determine the rounded digit

• 2. Pay attention to the digits afterward (right). If the digit shows the numbers 0, 1, 2, 3 or 4, then the digit to be rounded is fixed, and the digit on the right is 0

• 3. If the digit on the right shows the numbers 5, 6, 7, 8 or 9, then the digit to be rounded is added to one, and the digit on the right side is made all 0

In rounding the nearest hundreds number, then we see the digit in the number tens (right of the digit hundreds), if it is worth 0, 1, 2, 3 or 4, then it remains, but if it shows numbers 5, 6, 7, 8 or 9, then the digit to be rounded is added one, and the right-hand side is 0

At 678, the hundreds place is 6, and the number digit tens is 7

So that number 6 is rounded to 7 and the right digit is 0,

Rounding up becomes:

678 ---> 700
