How do you regroup 607 -568

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 .

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
