If you increase the hundreds digit in the number 189 by 5, then what number will you get?
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: Given number is 189. The hundreds digit is the one in the third column from the right.
Step 2: We increase this digit by 5, so the hundreds digit becomes 6.
Step 3: We reconstruct the number with the updated hundreds digit, maintaining the tens and ones digits as they are: 6 (hundreds) + 8 (tens) + 9 (ones).
Therefore, the new number is .
What number do the blue squares below represent?
Count positions from right to left: the first digit is ones, second is tens, third is hundreds. In 189, the digit 1 is in the hundreds place because it's the third digit from the right.
If adding would make a digit exceed 9, you'd need to carry over to the next place value. For example, if the hundreds digit was 7 and you added 5, you'd get 12, so write 2 in hundreds and carry 1 to thousands.
Only the hundreds digit was specified to change. The tens digit (8) and ones digit (9) stay exactly the same because the problem only asks to modify the hundreds place.
That works for this problem! Since 500 represents 5 in the hundreds place, adding gives the same result. This is a great shortcut method!
The digit is just the symbol (like 1), but place value tells you what it's worth based on position. In 189, the digit 1 has a place value of 100 because it's in the hundreds position.
