how would you regroup 4 tens to find the difference between 341 and 228
I'd
To find the difference between 341 and 228 by regrouping tens, you would start by writing both numbers vertically, aligning them by place value:
341
- 228
Next, we look at the ones place and see that 1 cannot be subtracted from 8 since 1 is less than 8. Therefore, we need to regroup from the tens place.
In order to regroup, we borrow 10 from the tens place in the hundreds column. We can then add it to the ones place, making the 1 in the ones place equal to 11.
Now, our equation looks like this:
3 3
- 22 8
Now, we can subtract the numbers in each place value from right to left:
Step 1: In the ones place, 3 minus 8 is -5. Since we have regrouped, we keep track of this negative value.
3
- 22 8
___________
-5
Step 2: In the tens place, 3 minus 2 is 1.
1
- 22 8
___________
-5
Step 3: In the hundreds place, 3 minus 2 is 1.
11
- 22 8
___________
-5
Therefore, the difference between 341 and 228 is -113.
