Answer:
By changing group of ones into tens
Step-by-step explanation:
Regrouping refers to changing group of ones into tens to make subtraction easy.
Here, we need to regroup 607 -568 .
In subtraction, we start subtracting digits from ones place.
In number 607, digit at ones place is 7 and in 568, digit at ones place is 8.We can't subtract 8 from 7, so, we will try to borrow 1 from the digit at tens place in 607, but digit at tens place in 607 is 0, so it's possible to take 1 from 0.
So, first we will take 1 from 6 ( digit at hundreds place in 607 is 6 such that 6 becomes 5 ) to 0 at tens place which will become 10 then take 1 from 10 to 7 which will then become 17.
Then , we will subtract 8 from 17.
From the figure:
Cross out the 6, make it a 5 and shift 1 which we have subtracted from 6 to 0 such that 0 becomes 10 then cross the 10, make it a 9 and shift 1 which we have subtracted from 10 to 7 such that 7 becomes seventeen .
