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 .

the answer is 375 miles

step-by-step explanation:

hello 0xxbadwolfxx0,

2.6 x 10^9 is 2,600,000,000.

1.3 x 10^2 is 130

multiplying 130 and 2,600,000,000 would simply give you 200,000,000,000.

therefore, the answer would be d. 2.0 × 10^11.

i hope i ! warm regards, mae.
