Roundeach number to the face of the bold-faced digit.what deos it mean
If the number was 9260, and the 2 was in bold, rounding would give you 9300. If the 9 was in bold, you would round to 9000.
I hope this helps.
When we say "round each number to the face of the bold-faced digit," it means we are rounding each number to the nearest multiple of 10, 100, 1000, etc., depending on the position of the bold-faced digit.
To understand this better, let's consider an example:
Example: Round the number 456,789 to the face of the bold-faced digit.
In this case, we have a bold-faced digit, which is the 5 in the tens place. To round the number to the face of this digit, we need to look at the digit to the immediate right of it, which is the 6.
Since the digit 6 is greater than or equal to 5, we will round the number up. Therefore, we replace the digit 5 and all the digits to its right with 0s, making the number 460,000.
So, when rounding to the face of the bold-faced digit, we ignore all digits to the right of the bold-faced digit and replace them with 0s if the digit to its right is 5 or greater. If the digit to its right is less than 5, we keep the bold-faced digit and also replace the digits to its right with 0s.
It's important to note that when a number is rounded to the face of a bold-faced digit, the value of the bold-faced digit remains the same, and only the digits to its right are changed.
